The Stenzelberg (originally: Steintelberg ) is a 287 meter high mountain in the Siebengebirge . It is located southwest of the Königswinter district of Heisterbacherrott near the Heisterbach monastery .

Geologically, the Stenzelberg is a spring crest made of the volcanic rock latite , whereby the rising magma did not reach the surface of the earth, but got stuck in the surrounding tuff cover rock . The softer tuff was later removed by erosion and the harder latite exposed.

The Stenzelberg has been used as a quarry for quartz latite since the 11th century . The stone was used for the provost church in Oberpleis , the Nikolauskapelle in Heisterbacherrott and the Bonn Minster , and later also for the churches in Nieder- , Oberdollendorf and Asbach . The Heisterbacher Hof in Königswinter is one of the other buildings built in Stenzelberger Latit .

The quarry operation ended in 1931. After the quarries were closed, a characteristic landscape developed on the Stenzelberg that offers the special flora and fauna of a dry biotope.

In particular, the steep rock faces and free-standing "walkers" made the mountain a popular climbing area in the 1980s and 1990s.

Climbing on the Stenzelberg has been expressly forbidden since June 2005. Previously, the Rhein-Sieg district had tolerated climbing, although the Stenzelberg, like the entire Siebengebirge, had been a designated nature reserve (NSG) since 1920 . The climbing ban was made necessary by the new nature reserve ordinance in the course of the recognition of the Siebengebirge as FFH area 5309-301 ( Fauna-Flora-Habitat ) of the European Union. In particular, the occurrence of the wall lizard was worried and egg-laying places at the field feet were destroyed. Despite the ban, there was illegal climbing after 2005. The forest office has therefore closed the path to the rocks.
