The Partizan Stadium is a football and athletics stadium in Beograd, originally named JNA Stadium (Stadium of the Yugoslav People’s Army). Mihajlo Janković and Kosta Popović were still little known as architects, and it came as a surprise when they were awarded the contract. They followed the principles of functionalism. Construction of the stadium began in 1948, and it was officially opened in the following year with an international football match between Yugoslavia and France. It was not completed, however, until 1951. The stadium originally had a capacity of about 55,000 spectators. After renovation, it was reduced to about 30,000 seats due to new security regulations. The pitch measures 105 x 70 meters and the stands have 30 rows of seats with 30 entrances for spectators.
