The stadium is best known for being the center of activities in the 1952 Summer Olympics. It was built however to host the 1940 Summer Olympics, which were moved from Tokyo to Helsinki before being cancelled due to World War II. The stadium was also the venue for the first World Athletics Championships in 1983 as well as for the 2005 World Championships in Athletics. It hosted both the 1971 European Athletics Championships and the European Athletics Championships in 1994. It is also the home stadium of the Finland national football team.
