Germany: The Town of Wittstock/Dosse

Wittstock/Dosse is a town in the Ostprignitz-Ruppin district, in north-western Brandenburg in Germany.
The town's main historic monument is the Brick Gothic St Mary's Church, dating back to c. 1240.
Significantly enlarged as a hall church in the late 13th century and repleted with a carved altar by Claus Berg, it was used as a cathedral by the Havelberg bishops.
The Bishop's Castle was greatly restored in the 1990s and today houses a Thirty Years' War museum. Much of the elaborate late medieval defences still surround the old centre, including a 13th-century gate tower, the Daberburg bergfried north of the town, and a 2,500 metres (8,200 ft) long city wall. The wall's height, originally 11 metres (36 ft), today is about 4 to 7 metres.
