Bregenz's landmark in the Upper Town, the Martinsturm (St. Martin's Tower), offers a wonderful panoramic view of the mountains, the city, and the lake.
The interior of the tower is also worth seeing: The permanent exhibition "Bregenz. City on Lake Constance" on the first floor, as well as the regularly held special exhibitions in the former watchman's apartment, provide a deep insight into Bregenz's city culture and history.
In addition, religious celebrations such as weddings and baptisms take place in St. Martin's Chapel.
