The interior of the Church of the Rock is an architectural oddity. Above the nave is a massive copper dome resembling a Chinese wok. The skylight along the edges bathes the Temppeliaukio Church with natural light. The walls are exposed stone, giving the appearance of a fresh excavation site. And the altar is an ice-age crevice. Perhaps most surprising about this design by the Suomalainen brothers are the wonderful acoustics. This is a great venue for concerts. The Church of the Rock is a curious treat to behold!
