The Töölö church was designed by architect, Hilding Ekelund. It was originally built as a parish building and dedicated as a church only when Töölö and its northern backwoods were separated off as their own parish in 1941.

Ekelund's interest in early Italian architecture is visible in the way in which the hall-like space connects with undecorated, well-thought-out details. The frame of the plastered brick church is rectangular in shape. A semi-circular choir separates off from it. The church hall is covered with a flat roof. The whole is symmetrical in a disciplined way. The decision to include a kitchen in a church building bears witness to a change in the ecclesiastical life, and it attracted attention when the church was being completed.

A concrete relief, Taivaalliset pidot (Heavenly feast). by artist, Gunnar Finne is placed above the entrance. The foyer is decorated by artist, Gunnar Forsström's, glass paintings and Paavo Leinonen's wall painting. In the church hall are found sculptor. Carl Wilhelms', apostle reliefs of Peter, Paul, Andrew, and Thomas. Artist, Nina Terno's, shepherd composition and Gunnar Finne's gilded wood sculpture, Ylösnoussut Kristus (Resurrected Christ) were later placed in the baptism chapel.

The Altar wall was supposed to have a wall painting by artist Henry Ericsson, but the work remained unfinished because the artist died in a car accident. There is only a partial sketch of the original plan. A large picture of the Crucifixion was obtained from Bavaria's Oberhammergau to serve as an altarpiece. The communion set was designed by Henry Ericsson (1928-1932) and the altar textiles by textile artist, Dora Jung.

There are two church bells in the Töölö church. The original church organ was made by the Kangasala organ factory in 1930. The current organ is from 1981 and was made by the organ builder, Veikko Virtanen. It has 26 stops.

In addition to the church itself, the building comprises baptism and wedding chapels, a large and a small parish meeting hall, and meeting and club facilities. In the basement of the church is the legendary meeting place, Pärinäpirtti, familiar from many Helsinki residents' youths. The church is used by the Töölö parish.

Celebrations at the church

Members of the church can organise a baptism, a wedding or a funeral free of charge in the church.
