A Ländchen is the German name given to several Ice Age plateaux in the Havelland region, which climb to over 70 metres above the formerly marshy urstromtal levels (old glacial meltwater valleys) of the Havelland Luch and the Rhinluch. The difference between these Ländchen and the surrounding countryside is even more marked because of the different land uses to which they are put. Extensive pastures in the lowlands contrast with the arable fields and woods on the low hills. Geologically they are largely complete formations of ground moraine from the Saale and Weichselian glaciations that, in places, are covered by gently rolling end moraines.
