 The Weser forms the border with the former.One peculiarity in the town's location is to be found at the constituent community of Würgassen, which lies on the Weser's right (here, north) bank, which would actually mean that the community were in Lower Saxony had it not been for the way a long-standing boundary dispute was settled in 1837.Even today, the boundary does not quite put all the community in North Rhine-Westphalia; the local Shooting Brotherhood's shooting range still lies partly in North Rhine-Westphalia and partly in Lower Saxony.
