Temppeliaukio Church is a Lutheran Church in the Toolo neighborhood of Helsinki. The church was designed by architects and brothers Timo and Tuomo and opened in 1969. Built directly into solid rock, it is also known as the Church of the Rock.
The Temppeliaukio church is one of the most popular tourist attractions in the city; half a million people visit it annually. The stone-hewn church is located in the heart of Helsinki. Maintaining the original character of the square is the fundamental concept behind the building. The idiosyncratic choice of form has made it a favourite with professionals and aficionados of architecture.
