Temppeliaukion kirkko and its copper dome in the Helsinki rock
Published on 08/22/2026 at 15:08 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Temppeliaukion kirkko in Helsinki is a Lutheran church carved directly into the city’s granite bedrock, where natural rock walls and a low copper dome form a single enclosed space dating from 1969. Designed by the Finnish architect brothers Timo and Tuomo Suomalainen, it turns the exposed bedrock of the Töölö district into the main material of the sanctuary.
