Tel Aviv's White City: A Bauhaus Architectural History

Conservation of 20th-century heritage presents unique challenges compared to older periods. The explosion of construction and architectural innovation in the 20th century, including new construction techniques and materials, creates a vast array of questions about classification and intervention. Unlike older periods where more time has allowed for reflection and established doctrines, 20th-century heritage requires new approaches. The creation of dedicated structures like clusters represents a significant advancement, enabling more sustained and systematic engagement with heritage issues through interdisciplinary cooperation.

Like all construction materials, reinforced concrete inevitably undergoes a lifecycle that requires maintenance and restoration. Italy currently lacks a formal registry of national monuments made of reinforced concrete, unlike other countries that have established such protections. This absence creates challenges for preserving the architectural heritage of reinforced concrete structures, as there are no standardized guidelines for their conservation and restoration.

Reinforced concrete is fundamentally incompatible with historical structures because it acts like a wedge (ariete) during seismic events, causing walls to collapse. The concrete's greater hardness compared to traditional materials like stone, brick, and lime mortar creates structural problems that compromise rather than protect heritage buildings.

Early 20th century concrete buildings, constructed between the late 19th and 1960s, require specialized conservation strategies due to their unique experimental nature, including hand-mixed concrete with higher porosity that leads to micro-cracks and corrosion; effective preservation involves minimal intervention, maintaining original materials while adapting structures for contemporary use, as demonstrated by the Phoenix Warehouse restoration in Rotterdam which preserved its historic industrial character while transforming it into a modern cultural center.

This segment examines the problem of reinforced concrete in historical masonry structures. It covers: (1) The loss of masonry construction knowledge in the 20th century, (2) The properties of masonry as a material: it is not homogeneous, not elastic, not isotropic, cannot have elastic constants defined, is normally cracked, and must work in compression, (3) The role of cracks in masonry as a way of adapting to movement, (4) The example of the Galician church that settled in an extreme manner, (5) The problem of reinforced concrete added to masonry structures since the 1960s, (6) The case of L'Aquila Cathedral's vault that survived the earthquake without cracking, (7) The current trend of removing reinforced concrete from structures like Santiago Cathedral's Obradoiro facade, and (8) The need to return to traditional masonry knowledge.

Modernist architects applied their theories to real-world urban planning. In 1947, Le Corbusier designed Chandigarh, India's new capital, using the human body as a model with government as the head and commercial areas as the heart. The city was divided into sectors like a five-pointed star. In Brazil, Lucio Costa won the competition to design Brasília, creating a city shaped like an airplane with government buildings in the fuselage and residential areas in the wings.

Brasília's design was based on five fundamental modernist principles: (1) Pilotis - elevated structures that free the ground floor for circulation; (2) Free plan - interior spaces without load-bearing walls; (3) Free facade - exterior walls that do not support the structure; (4) Horizontal windows - long horizontal bands of glass; (5) Garden roof - rooftop gardens providing green spaces. These principles were first applied in Rio de Janeiro before being used in Brasília. The Rodoviária exemplifies these principles, with its elevated structure allowing vehicles to pass underneath while creating a dramatic urban space. Brasília's urban planning was influenced by Chandigarh, India, designed by Le Corbusier in the 1950s, which established the rationalist principles of organized superblocks, wide avenues, and functional zoning. Both cities represent the modernist urban planning movement, featuring organized superblocks, wide avenues, and functional zoning.

Traditionally, examples of modern architecture in post-colonial contexts have been showcase examples like Chandigarh, Brasilia, etc. Modern architecture is only seen to have shaped the national debate or post-colonial context symbolically—it represents Western values and is either oppressive or seen as good depending on perspective. The debate is limited to symbolic value of whether symbolism was appropriate. What misses is that before these capitals are made, there's a whole discourse in which nations were very much invested and international institutions were very much invested, bringing in architects to set up processes which cannot be represented—buildings in some cases were not even made, just plans and reports circulated. How can architectural history now look at these archives and understand architects? These archives have been traditionally ignored by historians, and it's high time for historians to jump in.

International style was linked to breaking with artistic tradition mixed with new construction technologies. Brazilian modern architecture happened simultaneously with international style but was supported by a generation wanting to create new architecture for Brazil's identity. Unlike reactionary movements opposing international style in the 1960s, Brazilian modern architecture remained connected to history, place, and tradition, distinguishing it from purely international approaches.

Casablanca (Morocco) and Chandigarh (India) serve as comparative case studies constructed almost simultaneously after independence. A key finding is that citizens in these periods were making their voices heard, demanding that progress not be reserved for particular classes but be available to all citizens. This changed architecture and urban design radically, as citizens could no longer be considered mute subjects but became active participants with agency in the built environment. The modernist project is fundamentally a social and political project wedded to creating improved societies through housing and civic space.

Tel Aviv, founded in 1909 on Mediterranean sand dunes, represents the most radical implementation of modernist architecture in the world. City planner Sir Patrick Geddes designed it as a European-style garden city with freestanding houses and boulevards, constructing buildings on stilts to address the unstable terrain. The Bauhaus principle 'form follows function' rejected historical ornamentation in favor of functional, rational design. Approximately 4,000 Bauhaus-style buildings were constructed between 1931-1956, making Tel Aviv the largest collection of this architecture globally. Architects like Dorf Karmi, Richard Kaufmann, and Arie Sharon (who fled the Nazi regime) adapted European modernism to local conditions, creating a unique urban identity. The city's name 'Neuland' (New Land) reflects its utopian vision of a modern, light-filled, proportionally organized environment where every element serves a specific purpose.

Modernist city planning, dominant in the second half of the 20th century, promoted harmful principles: cities are bad, freestanding buildings are good, streets are bad, and land uses (residence, work, recreation, transport) must be completely separated. Brasilia exemplifies this 'Brasilia syndrome'—cities looking impressive from above but failing at ground level. Unlike traditional cities that evolved organically from human activity (life → space → buildings), modernist cities followed the reverse order (buildings → landscaping → rarely life). Despite calling humans 'modern,' our biological needs haven't changed—we remain walking animals with horizontal spatial awareness. Modernists discarded all knowledge about how people actually behave in cities, assuming everything needed to be completely different.

Theodor Herzl, a Viennese Jewish journalist, conceived the idea that Jews from all countries should gather in Palestine to form a national political entity. By the end of the 19th century, he issued 'The State of the Jews' manifesto. In 1902, he published 'Altneuland' (Old New Land), a visionary novel describing a transformed Palestine with modern infrastructure. The novel deeply affected Jews worldwide and inspired immigration. In 1909-1910, the first Jewish settlement outside Jaffa was established, initially called 'Auzat House Mansion,' and in 1910 was officially named 'Tel Aviv'—the first city in the world directly named after a book. The 'White City' concept emerged from an exhibition by art historian Mik Levine at the Tel Aviv Museum of Art in 1984, highlighting modernist architecture from the 1930s. In 2004, UNESCO included Tel Aviv's White City in its modernist heritage list. Nitsa Smoke, an architect trained in Italy, organized a vast project to classify and document all buildings from the 1930s. She published 'Dwelling on the Dunes' and created a narrative emphasizing that Tel Aviv was built on sand and dunes, a 'noman's land' not on the expense of anyone. She emphasized only one influence: the Bauhaus. This narrative served a political agenda: within Jewish hierarchies, those from Germany and Austria were considered more cultivated. Additionally, both Jews in Palestine and Bauhaus in Germany were victims of the Nazis, so recreating Bauhaus represented victory over the Nazis. The White City narrative creates a geography where only certain places are recognized and preserved. The old city of Jaffa, with its 3,000-4,000 year old history, contains no buildings inscribed within preservation frameworks. From all of Tel Aviv's 100-180 year history, only 8-9 years (1930-1939) are celebrated—the period when modernist architecture was built before World War II stopped construction.

The 'White City' in Tel Aviv is a UNESCO World Heritage Site recognizing more than 4,000 Bauhaus or International Style buildings constructed in the city during the 1930s and 1940s. Tel Aviv has the largest number of Bauhaus buildings in the world. This architectural heritage represents a unique blend of modernist design adapted to local conditions and cultural influences.

The modernist city operates as a living organism with a dynamic metabolism that continuously evolves through the interplay of tangible architecture and intangible cultural practices, as exemplified by Tel Aviv's White City, which combines garden city planning principles with international style architecture to create a unique urban environment where conservation must balance physical preservation with social and ecological considerations.
