The second stage of the long distance hiking trail Rheinsteig leads from Oberdollendorf through the Mühlental valley up to Heisterbach Monastery. Of course, you can also drive up, Heisterbach Abbey has a parking lot and a nicely designed bus stop of the RSVG line 520.
You may have seen the choir ruin of Heisterbach on picture postcards or flyers about Siebengebirge tours. Once, the Heisterbach’s abbey church was the biggest in our region, surpassed only by the gothic cathedral in Cologne. The famous choir ruin is all that has remained.
Not much has remained of Mount Stenzelberg. Already in the Middle Ages the Cistercian monks of Heisterbachgained stones there to build their enormous abbey church. For centuries the quarry continued, even after 1908, when the quarries on Mount Petersberg were closed.
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.
