The Dominican Island or Constance Island is an island in Lake Constance immediately east of the city of Constance. With an area of 1.8 hectares, it is one of the smaller islands in the lake. The island is separated from the city center by a six-metre-wide (20 ft) channel, and connected to it by a bridge. The island is dominated by the Steigenberger hotel, which is housed in the former Dominican convent.
