Ravensberg Basin
The Ravensberg Basin or Ravensberg Hills is a natural region in the governorate of Detmold in the northeastern part of the German state of North Rhine-Westphalia; small elements also fall within the neighbouring state of Lower Saxony. It is part of the lower Weser Uplands and includes the hilly basin country between the Wiehen Hills in the north, Lippe Uplands in the east, Teutoburg Forest in the south and Osnabrück Hills in the west. The heart of the Ravensberg Basin is almost coincident with the cultural region of the Ravensberg Land.
