Aalto planned the church also for other activities in the parish besides services. Therefore the church can be divided into three parts. In the church there are seats for 800 persons. The windows and lightning are high up, which creates fascinating display of light and shadow. The Church of the Three Crosses was completed in 1957.
The stained glass on the ceiling is as old as the church and also designed by Alvar Aalto. (Textsource: Parish of Imatra)
