Quarried out of the natural bedrock, Temppeliaukio Church is one of Helsinki's most popular tourist attractions. The interior walls are created naturally by the rock. The church was designed by architects Timo and Tuomo Suomalainen and opened in 1969. Due to its excellent acoustics the church is a popular venue for concerts. - in: http://www.visithelsinki.fi/In_English/Visitor/See/Main_attractions.iw3?showmodul=162&Matko_pid=227
