Introduction
The post-WWII period was marked by reconstructions and the advancement of the welfare state in the West and the socialist state in the East. Despite numerous collaborations between architects from both sides of the Iron Curtain, many dilemmas concerning architecture and its role in development projects remained unresolved. The article analyses how, after the WWII, the inter-bloc collaboration of architects in the context of the UIA (International Union of Architects) allowed for a fruitful exchange of ideas while at the same time its protagonists produced a discourse that made the intertwinement between architecture and ideology an untouchable subject. A similar situation can be discerned in the proceedings of the AYP (American-Yugoslav Project), a 1960s bilateral project for developing Cold War planning methodologies. The Slovenian architects worked within both conflicting conditions in Yugoslavia and abroad given the urgency for reconstruction and modernization. The socialist project collapsed by the 1990s, but its architectural achievements stayed, including the ones in Yugoslavia. However, the transition from socialism to capitalism changed the symbolic framework of their meaning. Since they were built to represent values antithetical to the ones of capitalism, their perception was accompanied by an embedded sense of irony. The same sentiment, however, can be traced back precisely to the fractures of the discourses and the failures of Cold War planning. The article therefore focuses on elucidating them through examining specific historical moments in Slovenian architectural history, which at the same time show how ideology co-shaped socio-political relations with architecture, both locally and globally. The first part is devoted to the question of beginning of the activities of the UIA immediately after WWII and to a reflection on the involvement of Slovenian architects in it. The circumstances hindered a thorough reflection on the fundamental relationship between architecture and ideology, thereby separating the discussion of architectural form from its purpose and various social realities. This became particularly evident during the UIA's activities in Morocco in 1951, which are explored in the second part of the paper. The third part of the article focuses on the question of spatial planning strategies during the Cold War, which were conditioned precisely by economic interest of the Eastern and Western blocs. The evolving dynamics of spatial planning, marked by larger-scale projects and organized international networking, often led to ironic situations due to conflicting ideological positions of those involved. This irony highlighted the dual nature of architecture, which both anticipated and co-shaped the transitions of the 1990s. The shifting meanings evident in these historical accounts added to the irony of contemporary perceptions.
Changing Perceptions
It is axiomatic that architecture can be simultaneously perceived as a physical and symbolic object. When a situation arises in which an architectural form is seen as a vehicle for values antithetical to those rendered at the time of its construction, irony cannot be dismissed as mere amusement. The fact that the same building can influence different modes of perception over time raises the question of its content and purpose within a wider spatial context that is directly linked to visions of progress and thus to constant technological and social transformations. There's a certain irony in the numerous (re)constructions that no longer inspire confidence in a fair and hopeful future. Contemporary spatial effects are accelerated or decelerated by the voraciousness of a commodified fragmental—image-biased—media. Often overlooked is the evolution of digital technologies related to architectural design and its two parallel trajectories, both of which were shaped after the WWII. One is related to architectural form, the other, however, concerns less visible but no less important spatial planning methodologies.
The process of organizing the exhibition on the architecture of Yugoslavia for the occasion of the second UIA Congress in September 1951 provides an illustrative example concerning the role of modernist ideas of Slovenian architects in a specific geo-political situation. Despite the initial UIA ambitions to build a new, more collaborative world with architecture, the discourse in the UIA's international arena suggests that these goals were not easily achievable. As the protagonists of the UIA tried to avoid political questions focusing on formal issues, a discursive gap was produced hindering a meaningful and supportive inter-bloc collaboration. The situation made it difficult to reflect on the fundamental interplay between architecture and ideology, which consequently distanced the question of architectural form from purpose and different social realities. When UIA’s activities took place in Morocco in 1951, there Slovenian architects organized an exhibition on Yugoslav architecture presenting architectural influences of the east and west, showing spaces of social inclusion, urbanization, folklore, media, etc.; none of which concerned economic issues.
When advanced methodologies of regional planning began to take hold in the mid-1960s, American and Slovenian architects adapted them for societal planning of Yugoslav socialism in the context of the AYP. By this time, planning methodologies had become a cross-disciplinary field, whose implementations gradually included the use of computer technology. As a collaborative project, the AYP had an impact on several fronts–in Yugoslavia it influenced the role of architects in the design of development projects, in America the lessons learned from the AYP were incorporated in the formulation of planning theory; it further evolved in the context of John Hopkins’ University planning programs, and at the same time the findings of the AYP were amongst several that co-shaped the UN's global development guidelines, which contributed to the expansion of the American sphere of influence beyond the Iron Curtain.
The AYP is thus a symptom of the times, from which it is possible to discern how the conditions of societal planning in Yugoslavia transformed and reformed the role of architects in the production of space. In Ljubljana this was a period of intense modernization under socialism, with the conditions of spatial planning being redefined through professional activities (centered on rethinking the question of form in the new social context) and the effects of the economic forces of the Cold War (shaping planning methodologies to become more scientific, leading to the production of space becoming increasingly opaque and driven by top-down processes).
The evolving dynamics of spatial planning were closely intertwined with architecture
culture. Projects expanded in scale, and international networking became increasingly organized through numerous professional meetings and exhibitions. However, the differing ideological positions of the participants often led to ironic situations. In this context, design experiences, approaches, and architectural achievements were framed differently, and their perception altered and influenced a transfer of their meanings. This irony consequently reflects the dual nature of architecture, which not only anticipated but also laid the groundwork for the transitions of the 1990s. As a result, the meanings of these buildings shifted, and irony permeated everyday life.
UIA – A Democratic Organization of Workers in Architecture?[1]
The pioneering spirit of the architects of the post-war period, navigating between the interests of the Cold War, inevitably collided with the barriers of different ideologies in the context of East-West collaborations. One of such occasions was UIA. Since there was no easy answer to these questions, they were often avoided at professional meetings. Were the architects’ opinions valued equally in such situations? Could their exchange of expertise provide mutual support for their practices despite ideological differences? International engagement impacted the architects' standing in their respective countries by facilitating the sharing of knowledge on a rapidly advancing technological foundation. This influenced new ways of designing architectural form. However, despite rapid social changes, political topics were seldom addressed. Through many intense debates the view prevailed that only by avoiding political topics, the UIA could facilitate truly ‘professional discussions.’
The UIA congress was founded in June 1948 in Lausanne, Switzerland. With its headquarters in Paris, it aimed to bring architects together around the issue of post-war reconstruction on a global scale, regardless of nationality, ideology or architectural doctrine. After Lausanne, congresses were held first in Rabat, Morocco in 1951, in Lisbon, Portugal in 1953, in the Hague, the Netherlands in 1955, in Moscow, USSR in 1958, and so on, all over the world. The organization is still active today and is the only association of architects officially recognized by the United Nations. Architectural exhibitions have regularly accompanied all their congresses.[2] The driving force behind the organization was Pierre Vago. Vago’s efforts to enable all architects, without exception, to be involved, were marked by personal experience. He was born in Budapest in 1910 and later studied at the École Spéciale d'Architecture (ESA) in Paris, where he collaborated with Auguste Perret and worked for the magazine L'Architecture d'Aujourd'hui. During this time he maintained links with Eastern Europe, seeking opportunities for Soviet architects to join the UIA. The Bulgarian architect Luben Tonev and Helena Syrkus from Poland, one of CIAM’s protagonists, helped him in the process.[3]
This proved to be more challenging than anticipated. While the UIA sought to function as a bridge-building institution, it encountered ideological and political questions from the outset. A particularly contentious issue during the drafting of its statutes was the concept of democratic governance, with members expressing diverse views on its definition and significance. The divide was especially clear in discussions surrounding this topic, as the USSR and Eastern European delegations advocated for democratic principles, whereas delegates from France, Switzerland, Italy, and Belgium adopted an anti-democratic stance, as will be explored in more detail in the following sections. The argument for a democratic organization was emphasized by the USSR’s Karo Alabin's desire for the UIA to become an international bulwark for the authority of the architectural profession. This was accompanied by his observation – often made also in Yugoslavia – that architects in capitalist countries do not have the opportunity to develop their social goals through creative enterprise. Alabian, one of the first Soviet architects working within the UIA, and chief architect of the reconstruction of Stalingrad, appealed to the leadership to make the UIA "an association of progressive democratic organizations of workers in architecture who are fighting for lasting peace, the establishment of democracies and the development of culture." He envisioned the UIA's role as an important agent in promoting these values.[4]
His appeal was, however, rejected by a section of Western architects, notably Paul Vishcer and Ralph Walker, who argued that the UIA should not have political aims, as these might prevent the free exchange of opinions and ideas.[5] Culture, after all, had a different role in post-war socialism and capitalism. Opening debates on democracy and planning strategies along with the related financing of spatial development and infrastructure could lead to direct political engagement and ideological confrontations. The final UIA resolution of the Lausanne Congress underwent several heated debates and modifications. For example, Luben Tonev argued that the reconstruction of Europe required architects working hand in hand with technicians, engineers, specialists, and at the same time with economists, sociologists and politicians. And yet, the final text of the UIA resolution was worded differently. Architects were to work with engineers, economists, sociologists, lawyers and others; [6] politics and ideology were clearly topics to be avoided.
Some Socialist Architecture in Colonial Morocco
Yugoslavia joined the UIA in 1948 after it had been expelled from the Cominform and started to reorient its politics, which made UIA’s fractures even more notable.[7] When organizing the Second Congress, originally planned for 1949 in Warsaw, the Polish members halted preparations, partly because they opposed Yugoslavia's entry. The move was to some extent blackmail in light of the criticism of the UIA leadership when it refused to sign the Peace Declaration.[8] The main criticism was, however, directed at the organization and content of the second congress by Helena Syrkus, who opposed Yugoslavia's participation in the UIA as well.[9] The situation was resolved in 1951when the location for the venue was relocated in Rabat, Morocco, rather than Warsaw. Under the title "How Does the Architect Perform His New Tasks?", architectural production results were showcased in an exhibition by representatives from Brazil, Greece, England, the Netherlands, Italy, Morocco, Mexico, and Yugoslavia.
Rabat seemed a more appropriate venue for the UIA Congress. Morocco was at the time declaratively neither socialist nor capitalist, but nonetheless undergoing rapid political transformations regarding its striving for independence from French colonial rule. The exhibition, which became a standard accompanying program of the UIA congresses, did not show any projects from behind the Iron Curtain. Yugoslavia was the only socialist country to present its projects. After the federation started opening for collaborations with the west, architectural accomplishments and development projects in Yugoslavia were not the appropriate material for exhibitions and congresses in the Eastern bloc, but apparently convenient for the colonial context. Rabat was a less electrifying venue, as ideological issues were more easily overlooked in the face of immediate local problems.
The “Architecture of Yugoslavia” exhibition was organized by the Architecture Section of the Yugoslav Society of Engineers and Technicians. While many architects from all the republics of the federation participated in the preparation, the final editing was done by the Slovene architect Edvard Ravnikar, who was also the exhibition curator and author of the introductory text to the catalogue. The material covered the presentation of buildings, but also the organization of the state with the emphasis on modernization, vernacular architecture (interpreted as influenced by the east and west), the landscape, folk customs, etc. In short, architecture was the context in which modern technology and folklore, east and west, intertwined.[10]
Ravnikar, conceived of architecture as the foundation for culture and space as an artistic category, interpreted spatial compositions and structures as originating their modern form entwined with local craftsmanship, materials and forms. The exhibition presented several renovation projects and broader urban concepts that indicated social inclusion, while at the same time revealing the architects' sensitivity and attention for specific local conditions.
Yugoslavia was at the time a non-aligned country, whose conditions of political engagement relied on societal ownership of land and a self-managed economy after much property had been nationalized. This kind of information was, of course, not presented in the exhibition, which is why Ravnikar's commentary, not printed in the catalogue, is significant. He presented the cultural heritage developed under the influence of the West and East as those which architects had adapted, transformed and supplemented in accordance with the new conditions and as the basis of work for the future. He linked the achievements in the field of production of space to the efforts made to improve people's conditions, which expressed the progress made owing to the revolution in society, the economy and cultural life, emphasizing his regret that he had not been able to present the results of the economy at the venue as a basis for the general development of socialism.[11]
The endeavors of Slovenian architects within the UIA were bound with organizing their autonomous activities in Yugoslavia and the establishment of the Association of Architects of Slovenia. In the first post-war years, architecture was understood as a basic construction activity. Ravnikar, however, argued that architecture was not just about building functional volumes, but the artistic engagement with space, which was intrinsically linked to culture and social reality.[12] Without such an accompanying text on architecture, society, economy, and technology, the exhibition had a much different impact on the audience. Architectural form was, ironically, excluded from its relationship to the context it co-shaped and became attached to other themes that prevailed in the congress, such as Mediterranean space, urban morphology, horizontal density, the adaptation of architecture to different climate conditions and addressing the need for identity and social inclusion. This was interesting for many other architects who were involved in the architectural design of European cities, including several CIAM members. Among them Alberto Libera, who was at that time working on the reconstructions of the Tuscolano area in Rome.[13]
Another notable architect and the official reporter at the 1951 UIA congress, was Michel Ecochard. Ever since the 1930s architects in Morocco were confronted with the problem of the mass migration of people from rural areas to industrialized cities, which led to the construction of improvised settlements (Bidonvilles). Ecochard, who headed the Service de l'Urbanisme (Urban Planning Service) at the time, worked to restructure the areas and housing estates buildings by using new technologies. The development strategies were incomplete at the time and did not address the pressing social issues adequately. For the French authorities, the Moroccan population after the war became, above all, a new, cheap labor force with which to modernize the country, precisely because of internal migration and simultaneously because of the unstable economic situation in Europe.[14]
Ecochard nonetheless adapted the design of buildings to the specific ways of life of local cultures, thus contributing to the development of different architectural typologies for different populations; yet, these same typologies were, again ironically, based on existing definitions of cultural and racial differences and consequently the production of space embodied them. The latter led to the spatial organization of housing and urban plans in the 1950s, which divided the Moroccan population according to religion (Jews and Muslims) and Europeans as a single category according to different classes. Factory workers were, for example, separated from the ‘upper-class’ population.[15]
The varying roles of architects in the post-war context, where the urgency for reconstruction and technological advancement dictated a rampant pace of building, enabled diverse forms of engagement with social issues through architectural design. International networks were nothing new, but the onset of the Cold War provided a completely new context for architectural projects and gave way for new discursive framings of architecture. For architects in socialist countries creativity meant striving for social goals with architectural form. They were the ones who wanted a democratic international association for cultural workers, since the reality in their countries allowed them to act within the tight constraints of the five-year-plan. The UIA could have provided them greater recognition, as architects aspired for the advancement of architecture culture. For Western architects, the position of cultural workers as such was incomprehensible and they were not interested in raising the issue with politicians about their role. Their autonomy meant, above all, the autonomy to act as professionals in collaboration with other professionals, within the parameters of the capitalist (welfare) state. Formal issues and technology offered for them more than enough room for professional debates within UIA.
UIA was not the context to develop criticism of either system or ideology that depended on large scale investments and provided the architects with the opportunity to build. When focusing their arguments predominately on formal issues, the architects, ironically, reiterated old patterns of social divisions in space. The conditions under which societies modernized were different. Since the social conditions that considerably determined the architectural outcome were not presented at the congress, the situation in Morocco illustrated well, how socialist projects amongst many other could become just another set of formal ideas.
As the question of ideology remained unresolved, the presentation of socialist projects in Morocco and later in Western Europe carried an ironic undertone. The situation reveals how post-war discourse evolved through numerous professional meetings and exhibitions, creating a framework that rendered socialist architectural achievements intriguing within a capitalist context. This, in turn, established a parallel interpretation of architecture's symbolic meaning within professional circles, one that was completely detached from the conditions in which the buildings were originally conceived.
Reconsidering Democracies
Expert networks were just one of many factors influencing development projects in Europe; investment policies also played a crucial role. Following World War II, U.S. support was instrumental in directing financial investments toward the swift reconstruction and urbanization of the continent. This initiative was primarily aimed at rebuilding war-torn infrastructure and modernizing the European economy, reflecting America's strategic interests in fostering stability and preventing the spread of communism. Through substantial funding and resources, the U.S. sought to transform the continent's urban landscapes, laying the groundwork for a new economic order that emphasized modernization and growth in the post-war era. For architects, designing under such conditions was a first-time, unparalleled challenge. When the US announced the program for aid for the recovery, reconstruction and stabilization of the European economy known as the Marshall Plan, it initially did not exclude the USSR or other socialist countries. However, it soon became clear that, in line with the Truman Doctrine,[16] the US did not intend to support communism.[17]
In June 1947 negotiations between England, France and the USSR on the US proposal in Paris ended abruptly with harsh criticism of Molotov. Afterwards Moscow telegraphed its East European embassies with instructions that the people's democracies should ensure their own participation in the forthcoming Marshall Plan discussions, which they did and, in the end, rejected their involvement.[18] Yugoslavia never took part in these proceedings despite Stalin’s insistence.[19]
Ironically, within this context, the question of democracy emerged from the Soviet side. Molotov denounced the US aid system as undemocratic and as directed against popular democracies and prevented sovereign states from deciding on their own development prospects. US investment was directed towards the development of European regions (not countries) according to the needs of the US side:
“The implementation of the Marshall Plan will mean placing European countries under the economic and political control of the United States and direct interference in the internal affairs of those countries … this plan is an attempt to split Europe into two camps … to complete the formation of a bloc of several European countries hostile to the interests of the democratic countries of Eastern Europe and most particularly to the interests of the Soviet Union.”[20]
Yugoslavia did not join the Marshall Plan, nor did it participate in the Molotov Plan, which was organized by the Soviet Union in response to the American initiative later that year.
As with the UIA, Slovene architects did not identify entirely with one side or the other. However, given Yugoslavia's non-aligned stance, its cooperation with the US intensified after 1948. What did it mean for Yugoslavia that it refused to be a part of either plan, and how can the traces of Cold War be discerned in spatial planning? Weren’t both sides arguing for peace and democracy? Where was the battle ground? Democracies of the east, or the people’s democracies, as they called themselves, meaning people’s regimes in which means of production were publicly owned, were politically organized in the context of the Communist Party. The economy revolved around the question of their five-year plans. In democracies of the west means of production were mostly privately owned and peoples’ will manifested through elections by having the possibility to vote for different parties organized around free market economy. There was no societal planning in the US. Spatial planning was conditioned by free market economy.
The battle ground was really about the imaginary space on future development determined in the Cold War context and was co-shaped by architects when reinventing the production of space on large scale with planning methodologies for urbanization. The position of the Iron Curtain was, through these processes, determined by the decision of European countries to cooperate economically either with the US or USSR. The engagement of Slovene architects in this situation is particularly telling since Yugoslavia, again, maintained its between-the-blocs position. Their activities reveal the differences when trying to overcome them in the process of appropriating western planning techniques and striving to maintain the preconditions for a societal plan at the same time as will be discussed in the following paragraphs.
Adaptations
Of particular importance concerning the activities of Slovene architects was the East European exchange program, a fellowship program administered by the Ford Foundation initiated in 1951. The fellowship allowed Vladimir Braco Mušič of the UPI (Urban Planning Institute) to travel to the USA in 1964 to establish connections with American academics; in particular John W. Dykman, who later collaborated on the American-Yugoslav Project (AYP). By 1966, the Ford Foundation supported a bilateral project between the US and Yugoslav governments, the AYP. The project was launched as a regional planning initiative, a Cold War ‘democracy-building’ enterprise that aimed at transferring American planning methodologies to Eastern Europe. It provided a 2‑year grant to Cornell University faculty to work with the Ljubljana UPI on the question of regional planning. The protagonists of the project were Vladimir Braco Mušič (UPI) on the Yugoslav side, Dykman (Berkley) on the US side in the first year and Jack Fisher later (Cornell and Wayne State University).[21]
The Ford Foundation[22] saw the project as an opportunity to expand their influence in socialist countries—the so-called Iron Curtain—something they long desired. The AYP was intended to be a short-term investment in a politically neutral technology transfer that would showcase the superiority of Western science and provide a model for exporting American urban planning knowledge around the world. However, it became the Ford Foundation’s largest project in Eastern Europe before the fall of the Berlin Wall and showed that planning was indeed a very political process.[23]
How ideology and spatial planning intertwined in the Cold War arena was perhaps best illustrated with a comment by Louis Winnick, the economist, who played a major role in Ford Foundation’s investments:
“All things considered, American-Yugoslav collaboration presented Ford with an exceptional opportunity ‘to open doors and minds’ within Marxist Europe, a basic Foundation goal since the inception of its East European programs. Looking back, one could also adduce a certain irony in the notion that a Communist domain, where systemized planning approached a secular religion, was willing to concede a deficit in a critical dimension–spatial arrangements at the regional level. The irony heightened by the fact that Yugoslavia sought assistance not from the socialist or labor party regimes of West Europe, Scandinavia or Great Britain, or even from dirigiste France, but from what was, arguably, the Western world’s most free-wheeling and least planned society.”[24]
A deep irony was thus present already amid Cold War. The spatial planners in Yugoslavia sought collaboration with Western experts due to their advanced methodologies. However, the situation reveals a more complex dynamic. While Yugoslav planners were adapting and refining their approaches to develop socialist spaces, the knowledge exchange simultaneously provided Western investors with a deeper understanding of how socialist societies were organized. Ironically, this allowed Western investors to adjust their methodologies in ways that appealed to countries beyond the Iron Curtain. The discursive framework of the AYP thus transformed the meaning of development projects, making them attractive to both Western investors and Eastern European planners. This created an imagined professional reality, where, despite unresolved ideological differences, socialist contexts increasingly adopted Western-style development models. Today, after the collapse of socialism, this irony persists, illustrating that the forces shaping architecture were driven not only by professional meetings and debates but also by investments deeply intertwined with political agendas.
How did the project evolve and what were the problems? The original project was organized in the summer of 1966 to develop a regional planning research and training center in Ljubljana and bring American know-how in regional planning to Yugoslavia. In the years 1966–67 the goal of the project was to ‘contribute to the development of spatial planning in Yugoslavia by confronting the problems of the Yugoslav experts to the experience of the concepts of the American academy in the field.’[25] In more practical terms, the idea was to develop thoroughly professional plans with the emphasis on the quantification of economic and social factors for the Ljubljana region as a case study. At the time Ford aimed at establishing an interdisciplinary training and research program for young professional planners extending to Eastern Europe. The UPI of Ljubljana served as the administering agency, but it was also the Association of Yugoslav Planning Institutes, known as Zajednica, that provided Federal sponsorship and organized a Yugoslav “national” advisory committee for the project.
One of the scopes of the project was establishing an International Centre for Regional Planning Studies chartered as a Yugoslav legal entity. Its charter would provide for a board of directors composed of representatives of Yugoslav planning institutions as well as non-Yugoslav professionals, regional planners and researchers to enable research activities on regional planning problems: training of professional planners, regional scientists, economists, geographers, demographers, sociologists, architects, and administrative experts. This autonomous think-tank was to provide a scientific base for regional development. It was about laying the foundations for a regional planning institution that would cooperate internationally, connecting urban planners in the region with the American experts in the field.
Problems arose almost immediately, and they showed the basic differences in the approach to planning of socialist and capitalist contexts, whose futures would supposedly materialize differently in space. At the beginning the specialist were facing a seemingly unresolvable situation. Urban land was, according to the American planners, to derive its site value from the incremental gains of its location and was envisioned to be allocated to the most productive users according to the principle of ‘highest and best use.’ This was dismissed as completely irrelevant in Yugoslavia, where urban land was publicly owned and administratively distributed. In such circumstances the attribution of any value and price to land was an alien idea and caused a significant problem when starting the AYP since both parties were unable to communicate the basic starting point for planning.[26]
This was not the only predicament. To the US contingent un-priced land provided no clues to the rational spatial arrangement of economic activities. Likewise, housing, which in a market system is an economic good rationed by price and rent, was treated by socialist planners as a public good provided at a nominal charge, slated in the future to be a free commodity. Rent-income rations of 25% typical for the US context seemed like exploitation to the Yugoslavs by landlords and renters. Conversely, to the Americans, Yugoslavia’s closely packed three-generation households and the 10-year queue for a dwelling was evidence of underinvestment in housing, which, in a capital-short state, could be remedied by higher consumer outlays.[27]
The described difficulties were connected to the question of property and profit, and it was therefore necessary to establish a new common ground through methodologies in which it would be possible to overlap the interest of both the Western investors as well as socialist governments expanding the logic of the Marshall Plan, which was in the long run an economic success for the Americans. Yugoslavia needed the economy to recover, it needed investments but could not engage a free market economy with socialism. How could it modernize and instill a societal plan at the same time?
Research in regional planning procedure in the AYP relied on the analysis of the region through several parameters. One set of parameters (drawn as top-down in a diagram) was described as: economy, population, physical conditions and other factors. These factors were then reconsidered via alternative sets of data and evaluated via another set (drawn as bottom-up in the diagram). These parameters included: housing, work, transportation, agriculture, services and infrastructure. It is possible to interpret the two sets of parameters corresponding one to the US and the other to the Yugoslav analysis of the situation. In short, the Yugoslav planners recognized the immediate social challenges in developing space vis-à-vis the economy, which both sides accepted as a precondition for planning. The process was to be constantly considered, reconsidered and studied further via problems, objectives, indicators and measures (horizontal parameters). These were the key elements for the planning process and generating data based on applicable development factors reconsidered for the region of Ljubljana. In this phase they used the Lowry model adopted for the AYP developed by Ira S. Lowry, which quantified economic and social factors.[28]
Looking closely at the Lowry model, the computational link between the two views, it too quantified the analyses of the regions through its own set of parameters. These included additional aspects of development: travel time; population, employment, land use, attractiveness factors for population and population serving employment; work, shopping, special shopping, social recreation. Though the planners tested out different spatial patterns (corridors, linear, polycentric) when studying supposedly all possible factors that influenced urban growth, the Lowry model seemed to them as most efficient. In this process computing helped sorting out different sets of information. The inputs included details about the future transportation networks, location of future non-population serving employment (industry), and projected population estimates for the region. Outputs included distribution of population, population serving employment (services) and the amount of land consumed by various urban activities.[29]
The results of the Lowry analysis were presented as regional maps in which the program defined urban, suburban and rural areas in several stages. In the case of AYP regional development meant imagining urbanization for a wider Ljubljana metropolitan region. The boundaries of the computerized schemes did not in any case correspond to the boundaries of zones, municipalities, republic or the state in which people could potentially politically organize and state their opinion about different types of development transforming their immediate surroundings. Instead, this planning strategy envisioned a region in which intense urbanization was managed by experts whose decisions relied on pre-determined factors. Regional planning as such had nothing to do with people’s democracy nor with the notion of western democracy. It did, however, appear scientific, progressive, and appealing.
Aftermath
The AYP officially ended in 1970, when Ford withdrew its funding. But the ideas lived on. The AYP was the basis for the establishment of the Regional Planning Centre in Belgrade and Ljubljana under the auspices of the UN Economic and Social Council, conceived in the light of the 1086 C (XXXIX) resolution for developing research and training program in regional development. It envisioned assisting countries that were facing migration from rural areas to cities and to modernize their economies through industrialization and agricultural improvement programs.[30] The Yugoslav experience is one of many in this field, the aim of which was to develop compatible regional planning methods for around the world to unravel under UN sponsorship. The regional planning network created an infrastructure for planning, which included establishing UN Secretariats that from the 1970s onwards became a major player in international relations. They have had a significant influence on national policies but have been almost invisible since they have not been part of national governments. Their role in the contemporary regional planning as well as their influence on global governance is yet to be examined.[31]
Additionally, the AYP was significant in co-shaping the Johns Hopkins University programs at the Centre for Metropolitan Planning and Research by initiating a lasting engagement with Eastern Europe. When Fisher moved to Hopkins in 1972, he brought the AYP with him. (The Centre also engaged in planning the Belgrade Transportation Project during this period.) This not only enhanced Hopkins' academic and research portfolio but also solidified its reputation as a leader in urban studies with a unique international perspective on planning methods in a communist context. The collaboration led to a sustained relationship with Eastern Europe, embedding this international dimension into the university's strategic initiatives and academic activities.[32]
The work of architects within the UIA and AYP was symptomatic of its time and was defined by contradictions developed in a tense political climate. The nature of war is not to resolve contradictions, but rather for one side to impose its will upon the other. Thus, the professional activity of architects within the UIA left aside the question of ideology and architecture, allowing the discourse to focus pronominally on formal issues without seriously considering the economic effects on society. The situation around the AYP, however, was not so clear-cut. Parallel to trying to develop different models and strategies to even start working on the AYP there was also a constant negotiation about how and why decisions were being made and who was allowed to make them. We can see this in the procedure of planning already in the first stage of the project, in 1967–68, when both sides proposed two different stages of the ideal planning procedure.
For the American planners this included a macro, sector and project stage of planning process after which came directly planning of physical space. For the Yugoslav planners, however, after the spatial planning phase the stage was set for establishing a societal plan and a feedback loop to rethink the macro plan. This was in fact the background idea for complex diagrams developed in the final stage of AYP. The Lowry program later rationalized how these evaluations unfolded, but the Yugoslav side meticulously insisted on the feedback loop when it came to final decisions. They were to be made by people not systems or machines. Despite all the scientific parameters and ideologies, the architects insisted on maintaining conditions for the possibility of a societal plan to be reconsidered against macro-economic factors. This theoretically allowed for local institutions to influence development. Although this decision-making and coordination process was supposed to provide an inclusive starting point for societal planning, the practice was not as consistent.
The evolving dynamics of spatial planning during the post-war era consistently produced ironic outcomes, rooted in the conflicting ideological positions of those involved. These ironies underscored the dual nature of architecture, which both anticipated and helped shape the transitions of the 1990s. As socialist and capitalist architectural practices intersected, the symbolic meanings of buildings were often reframed, detached from their original context, and reinterpreted in ways that conflicted with their ideological foundations. Particularly, the collaboration between Yugoslav planners and Western experts highlighted this irony, as Western investors adapted socialist methodologies to suit their own agendas. This knowledge exchange, while rooted in ideological opposition, resulted in an unexpected alignment of practices across the Iron Curtain, with Western models influencing socialist contexts. The irony persists today, as the forces shaping architecture were not only professional but also deeply political, revealing how investment and ideological compromise played a central role in transforming both architectural meaning and urban development during the Cold War era. Moreover, the reality of international symposia, exhibitions, and investments was integral to establishing an imagined expert reality—one that continues to influence architectural and planning practices to this day.
