REUTERS/Marko Djurica Laundry hangs out to dry outside of Block 23 in an apartment neighbourhood in New Belgrade, Serbia, July 31, 2019. Brutalism, an architectural style popular in the 1950s and 1960s, based on crude, block-like forms cast from concrete was popular throughout the eastern bloc. After World War Two socialist Yugoslavia led by Josip Broz Tito set out to reconstruct a land destroyed by fighting. Residential blocks, hotels, civic centres and monuments all made of concrete shot up across the country. The architecture was supposed to show the power of a state between two worlds - Western democracy and the communist East, looking to forge its own path and create a socialist utopia.

Brutalism was popular throughout the eastern bloc but the former Yugoslavia made it its own - seizing on it as a way to forge a visual identity poised between East and West. Interest in the style is soaring - particularly since a 2018 exhibition in New York's Museum of Modern Art (MoMA) called Concrete Utopia: Architecture in Yugoslavia, 1948-1980. After World War Two socialist Yugoslavia led by Josip Broz Tito set out to reconstruct a land destroyed by fighting. Initially allied to the Soviet Union, Tito broke with Soviet leader Joseph Stalin in 1948. Residential blocks, hotels, civic centres and monuments all made of concrete shot up across the country. The architecture was supposed to show the power of a state between two worlds - Western democracy and the communist East, looking to forge its own path and create a socialist utopia. But after Tito died in 1980, and economic crisis took hold, the new elites sought to distance themselves from the socialist regime, including its architecture. In 1991 the series of wars began that led to the collapse of Yugoslavia. REUTERS/Marko Djurica SEARCH "ARCHITECTURE DJURICA" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.
