history

The brook was used for several centuries by farmers in the villages of Duvenstedt and Lemsahl-Mellingstedt as pasture and for cutting peat. At the end of the 17th century , the Tangstedt chancellery acquired commercial rights of use, which were replaced by 1887. At that time, the Brook was the preferred hunting area of the Wellingsbüttel landowners, the Jauch family , who leased it to their land and released the pheasants that still live in Brook and its surroundings. In 1925 Hamburg bought large parts of the Brookes, which at that time was still in the Stormarn district. The rest came to the Hanseatic city with the Greater Hamburg Law in 1937.
