Excavated directly into solid rock, the Temppeliaukio church is situated in the heart of Helsinki, at the end of Fredrikinkatu. Because of its special architecture, the church, completed in 1969, is one of the main attractions in Helsinki. The church hall is covered with a dome, lined with copper and supported on the rock walls by reinforced concrete beams. The interior walls are of rugged rock and rubble wall. Before noon, the light spreads from the row of windows surrounding the roof periphery to the altar wall, where an ice-age crevice serves as the altarpiece. Due to its excellent acoustics the church is a popular venue for concerts.
