'Vuoksenniska Church' by Alvar Aalto

1956-1958

Church of the Three Crosses (Kolmen Ristin kirkko; Vuoksenniska Church) is a Lutheran church in Kaukopää, Imatra, Finland. The church was designed by Alvar Aalto and completed in 1958. It's said to be Aalto's most original church design. The church gets its name from the 3 crosses at the altar.

The church consists of 3 consecutive halls which can be separated by sliding walls; this enables parts of the church to be used for parish activities during the week. The exterior of the church is white with a copper roofing.

Docomomo has listed the church as a significant example of modern architecture in Finland. The Finnish Heritage Agency has listed it as a nationally significant built heritage site. A committee designated by the Finnish Heritage Agency in 1998 to commemorate the centenary of Aalto's birth selected the church as 1 of the 5 most important buildings designed by the architect.

Designated a UNESCO World Heritage Site in 2026.
