Han-Sur-Lesse - Grottes de Han

The Grottes de Han were inhabited as far back as the Stone Age by people seeking refuge. Not until 1804 did four young men dare to venture further into the caves. During subsequent explorations over the following years the larger caverns with their stalagmites and stalactites were discovered. The grottos have been open to the public since 1856.

The system as it is known today consists of a series of intricate caverns with a total length of 10km/6mi, only 3km/2mi of which are accessible, some only since 1962. The dirt left on the ceiling in the oldest caves by the smoke and soot from torches is clearly visible but they remain extremely impressive thanks to the skillful illumination.
