The Piuskirche was built between 1964 and 1966 to plans by Franz Füeg. The 13 meter high cubic building has no windows - the outer walls between the steel supports beams consist of 888 slabs of 28mm thick, translucent, Greek marble. While the building appears almost white from the outside, the marble has rich yellow and orange tones from the inside.
The free standing 40 meter high bell tower is completely made of steel, like the supporting framework of the church. It houses 5 bells made by the "Erdinger Glockengießerei" near Munich, Germany.
