Helsinki Velodrome
It was built in 1938–1940 for the 1940 Summer Olympics which were cancelled due to World War II.After the war, it was a venue of the 1952 Summer Olympics for the track cycling and field hockey events.The original building was deemed inadequate during the games and additional space was quickly erected to accommodate the athletes and press.[1] Before the renovation of 1997–2000, the center area had a natural grass pitch and was used for soccer, hosting local teams like Ponnistus, Käpylän Pallo and Atlantis FC.[4] In 2010 a training pitch designated primarily for American football was opened in the near vicinity of the Helsinki Velodrome, making the area an unofficial American football center of Helsinki.
