The Bruderholz runs in a northeast-southwest direction and separates the Birstal from the Leimental . The gentle ridge belongs to the Sundgau hills and rises to a height of 391 meters, i.e. more than 100 meters above the neighboring valleys. It is slightly wavy and rises slightly towards the south. The Buremichelskopf forms a prominent point at 363 meters, northwest of the Bruderholz water tower . The Bruderholz is cultivated in the north. The Basel Bruderholz quarter and the Basel- Landschaft Bruderholz Hospital are also located there .
The subsoil and the valley floor consists of Cyrene marl ( Blue Latvian / Oligocene ) from the Tertiary . Above it there is gravel (partly Nagelfluh ) and, as a top layer, fine, yellowish dust, the loess / loess clay from the Ice Age ( Diluvium ). This surface layer is very fertile, and therefore rich fields and lush meadows extend on the plateau. In addition, the Bruderholz is one of the popular local recreation areas in Basel.
In 1815 a ski jump , called a battery , was built in the urban area and in 1926 the Bruderholz water tower, which can be seen from afar, was built nearby.
