Go on an adventure and plunge into a bygone era – this is what Silex’s offers you during descents into real Neolithic mines.
Are you ready to go back thousands of years?

Discover the story of the first miners by exploring the subsoils of Spiennes. A guide will accompany you through time ... A fall arrest harness and a helmet are provided to each visitor.

Booking is preferable! Indeed, for conservation reasons, only 5,500 people can go down each year. It’s therefore essential to book your descent beforehand.
