ON THIS DAY -- March 20 March 20, 1994: SOCCER - British soldiers cheer on the United Nations team during a match against FC Sarajevo, which was played in front of 20,000 fans in the former 1984 Winter Olympics Stadium Zetra. Eight years after the erstwhile Yugoslavia became the first socialist state to host the Winter Games, Sarajevo was at the heart of the Bosnian War which lasted until 1995. The match, which ended 4-0 in favour of the local team, was also marked by entertainment by British army parachutists and a Buckingham Palace band. "It's a very big event ... By this match today I believe we're advancing the peace process in Bosnia-Herzegovina and not just in Sarajevo," Britain's Michael Rose, the head the U.N. peacekeeping efforts in Bosnia, said.

Miodrag Zivkovic, 91, architect of the "Battle of Sutjeska" memorial monument, poses for a picture with the original maquette in his home in Belgrade, Serbia, February 27, 2019. Zivkovic, the sculptor of the 19 metre-high concrete Tjentiste memorial was among the first artists in the former Yugoslavia to use concrete. "It is stable material, resembling stone but it is easier to work with," he said. "For every project back in those days there was a national contest, and artists from all over the country had the opportunity to apply, and that competition produced quality."

Laundry hangs out to dry inside the Block 23, apartment neighbourhood in Belgrade, Serbia, July 31, 2019. 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.
