The Schlosskirche with its two 55 m high domed towers made from Rorschach sandstone is the landmark of Friedrichshafen. It was built by Christian Thumb from 1695 to 1701 and belongs to the famous Upper Swabian baroque buildings. Since 1812 it has been a protestant church. In 1944 it was partly destroyed by air raids, reconstructed from 1947 to 1951 and then given back to the Protestant community.
