The Swimming Stadium was designed by architect Jorma Järvi in the Functionalist style, which was prevalent during the 1930s.

According to the International Swimming Federation, the water temperature in the pool needed to be at least 22 °C, nowadays 27 °C.

[citation needed] The machinery to heat the outdoor pool was ordered from abroad, and the ship transporting them was sunk immediately after the war broke out.

However, when swimming teams or clubs come to practice at the Stadium, the 3 metre springboard may be reserved for their use.

The Swimming Stadium was also the scene for filming the popular Finnish youth television show Summeri during the years 2003–2009 and 2011.
