Geographically it covers the northern part of the
Sauerland hills and the lower land north of it, the 'Hellweg'. The rather flat land and very fertile
loess soil have made it an agricultural area from ancient times. The main rivers through the district are the
Ruhr, the
Lippe and the Möhne, which is dammed to form the
Möhne Reservoir. The highest elevation is in the area of
Warstein at 580m, while the lowest is the
Lippe valley at 65m. ==Coat of arms==
