The Church of the Three Crosses (also known as Vuoksenniska Church) is site number 012, and it is located in Imatra. The church was consecrated in 1958. The name of the church comes from the three white wooden crosses that stand in place of an altarpiece. The positions of the crosses and the nearby windows are designed in such a way that the shadows of the crosses are clearly projected onto the wall. The church is asymmetrical, and, for example, all but two of its windows are different.
The church suffers from a severe indoor air quality issue caused by moisture damage, and it has been temporarily closed at times during the 2020s. Currently, the church is open a few days a week for visitors, but parish services are not held there.
