Hanseatic city and the unofficial capital of the Altmark region. The characteristic brick buildings of the cathedral, St. Mary's, St. Jacob's and St. Peter's churches, St. Anne's and St. Catherine's churches, the town hall and the Tangermünde and Uenglingen gates were built during this period. The latter is, after Lübeck's Holsten Gate, probably the most architecturally attractive city gate of the North German Brick Gothic.
