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.
