With its two imposing cupola towers, which soar a proud 55 meters into the air, the castle church made of Rorschach sandstone is a real highlight. Built between 1695 and 1701, the interior impresses with its three-aisled pillared hall and stunning white stucco decoration. After being taken over by the evangelical church in 1812, the church suffered severe damage in an air raid in 1944, but was renovated from 1947 to 1951 and then returned to the evangelical community. Today the castle church is a well-known landmark of baroque construction in Upper Swabia.
Today's Friedrichshafen Castle was formerly a Benedictine monastery called Hofen. It was founded in the 11th century and converted into a summer residence for the kings of Württemberg in the 1820s. The complex is still owned by this noble family today. On Lake Constance lies the beautiful castle harbor pier, where the royal yachts were once moored.
