Wenceslas Square, Prague, Czechoslovakia 1960 Spartakiáda

Wikipedia:The Spartakiads in Czechoslovakia (Czech: Spartakiáda, Slovak: Spartakiáda) were mass gymnastics events, designed to celebrate the Red Army’s liberation of Czechoslovakia in 1945. They were organised by the Communist government as a replacement of the Sokol gatherings, which were disapproved by the regime and discontinued after World War II. The Spartakiads took place at the Strahov Stadium, the same place as the last pre-war Sokol gathering. The first Spartakiad took place in 1955, and was subsequently held every five years. The Spartakiad scheduled for 1970 was canceled in the wake of the Prague Spring and the beginning of normalization. Preparations for the Spartakiad scheduled for 1990 were interrupted by the Velvet Revolution, but the event still took place, although on a much smaller scale than the previous ones. Photo:
