January 7, 2023, View of Schloss Drachenburg

A little below the Plateau you will pass this vantage point of Drachenburg Castle on the way. The view of the (almost kitschy) castle with the Rhine and the Bonn skyline in the background is great. Photos from the small platform almost automatically have postcard quality.

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 designated as a nature reserve (NSG) since 1920. The climbing ban became necessary due to 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 concerned and egg-laying sites at the foothills of the fields were destroyed. Despite the ban, climbing continued illegally after 2005. The path to the rocks was therefore closed by the forestry department.

The Stenzelberg is geologically a spring dome from the volcanic rock Latit. The rising magma did not reach the earth's surface here, but got stuck in the surrounding tuff cover rock. The softer tuff was later eroded away, exposing the harder latite. The Stenzelberg has been used as a quarry since the 11th century, in which quartz latite rock was mined. The Heisterbach Abbey also operated a quarry on the Stenzelberg. The quarried material was also used to build the monastery buildings and the abbey church. Furthermore, rock from the Stenzelberg was used for the Propsteikirche in Oberpleis, the Nikolauskapelle in Heisterbacherrott and the Bonn Minster, and later also for the churches in Niederdollendorf, in Oberdollendorf and in Asbach. The operation of the quarry ended in 1931. Source: https://www.kuladig.de/Objectansicht/O-FJK-20100630-0032

The Stenzelberg has retained its attractiveness even after stone quarrying ended. Stones have not been quarried since 1931. Due to its picturesque rocky landscape, the Stenzelberg is still a popular destination for many hikes. In addition, the 287-meter-high summit offers habitat for animals such as smooth snakes and wall lizards. For this reason, it is kept free of shrub and tree growth.
