history
At the time of industrialization in the Kingdom of Hanover , two farmers' families from Altwarmbüchen mined clay in place of the later clay pit and burned bricks as a sideline for resale. In the early days of the German Empire, the architect and master mason Hermann Kaiser exploited the clay pit on a grand scale using a steam brick. In the area, under sands of low thickness, clays from the Lower Cretaceous are up to 350 meters thick .
After the First World War , the consul Carl Flemming acquired the company, which was the largest employer in Altwarmbüchen until it closed down in 1978. With the decommissioning of the degradation that has been mine drainage set, then the Tonkuhle with precipitation and ground water that filled. In 1985, the community was Isernhagen owner of a total of 11 hectares Tonkuhlengeländes that since 1969 the conservation area is Upper Wietze. The community had the site recultivated from 1991 to 1993 . In 1992, areas in the southern area were designated as specially protected biotopes . Since then, the natural area of the Tonkuhle has been of great importance as a retreat for endangered animal and plant species.
A brickworks for processing the excavated clay was located about 500 meters south of the clay pit on the other side of Hannoversche Strasse just before the Altwarmbüchener See lake that was created in the 1970s . Today the Green Ring runs along the former route for the carts between the clay pit and the brickworks. The brick buildings were almost completely demolished in 1982 and the area occupied with residential development. The former masters' house was preserved and served as a youth center under the name Jugendtreff Alte Ziegelei until 2010 .
