Weilberg, Siebengebirge, Königswinter
Abandoned quarry

Here we are at the abandoned quarry at Mount Weilberg, near the monastery of Heisterbach at the L268 street. In the 19th century and early 20th Century, basalt was mined here a stone that resists even hardest pressure. With the building of streets and railway lines, every time more basalt was demanded.

Back then, the Heisterbach Valley Railway transported the stones into the valley. The “railway and model railway enthusiasts Siebengebirge” have built a replica of quarry for the Brückenhof museum in Königswinter-Oberdollendorf, you can admire it in the museum or online: there are photos on the Brückenhof’s websitewww.brueckenhof.de, and there is a a video on YouTube.

The quarry at Mount Weilberg was one of the last to be closed. In 1922, the whole Siebengebirge came under protection. Here on the Weilberg, on 15 October 1971, the Siebengebirge was awarded the European Diploma of Protected Areas.

Today, you read “Geologischer Aufschluss” (geological outcrop) on the sign-posts. Here we can see the rock structure and get an idea of how the Siebengebirge came into being, for more information see volcanic origin.

The information board on the upper and lower plateau explain exactly what happened (in German). You can learn more about rocks and volcanism in the Siebengebirge in the VVS Nature Park house and on its website www.naturpark-siebengebirge.de (in German).
