August 16, 2026, Weilberg Stone Quarry and Stone Crusher Works Monument

Before the Siebengebirge became the first nature park in North Rhine-Westphalia in 1958, it experienced completely different times. For many years, the volcanic rock was highly sought after as a building material in the surrounding area and was therefore exploited accordingly. The quarry, visible a short distance later, to which the crushing plant documented here belonged, bears witness to this past.

It is not a natural cave and just an artificially expanded tunnel.

What today belongs to a strictly protected nature park - and may seem like a romantic backdrop to the hiker - was in earlier times a not-so-safe workplace: The volcanic rock formed the natural basis for a brisk trade in the coveted building material and had to be removed by painstaking manual labor.

The entrance area to the former monastery site, where the small remnant of the choir ruins is now a main attraction, leads from the street (bus stop and visitor/hikers' parking lot included) through the gatehouse, also known as the gatehouse.
