Neolithic flint mines of Spiennes

Listed by UNESCO in 2000, the Spiennes archaeological site is one of the oldest and largest centres for the extraction of flint in Europe. Dotted with thousands of mine shafts, the site extends over 250 acres at a distance of four miles from the city of Mons.

Digging mine shafts to as much as 16 metres in depth, Neolithic man invented techniques to extract large slabs of flint, in some cases weighing hundreds of kilos. He also developed techniques for cutting the flint, which are now recognised as early evidence of human ingenuity.

In the midst of beautiful greenery, the SILEX'S interpretive centre at the Neolithic flint mines of Spiennes will, from spring 2015, allow visitors to understand all facets of this internationally renowned archaeological site. Visitors will have the possibility to go on educational walks at surface level, visit the semi-permanent exhibition, and descend into a real Neolithic flint mine.
