Duivelsgrot

Duivelsgrot is a limestone quarry at Sint Pietersberg featuring a trapezoidal entrance with a round window set against white limestone cliffs. The interior contains extensive underground corridors and passages that branch throughout the site.

Starting in the 17th century, workers excavated this quarry by hand, creating an intricate network of tunnels. These passages later served as storage spaces and shelters for animals.

Local residents named this site Devil's Cave because the entrance resembles a skull-like face, especially when seen at dusk. This naming reflects how communities create folklore around striking natural features in their landscape.

The site lies about 400 meters north of Kanne cemetery and offers unrestricted access without entrance fees. Bring lighting equipment since the underground passages are dark.

This quarry sits so close to the Belgian border that the limestone mining network extends across national boundaries. The cross-border geological heritage demonstrates how people have extracted resources from both sides over centuries.
