The Olympic Stadium was designed in functionalistic style by the architects Yrjö Lindegren and Toivo Jäntti. Construction of the Olympic Stadium began in 1934 and it was completed in 1938, with the intent to host the 1940 Summer Olympics, which were moved from Tokyo to Helsinki before being cancelled due to World War II. It hosted the 1952 Summer Olympics over a decade later instead. The stadium was also to be the main venue for the cancelled 1943 Workers' Summer Olympiad.
