The Neolithic flint mines at Spiennes are the largest and earliest concentration of ancient mines in Europe. They cover more than 100 ha, and are inscribed on the UNESCO World Heritage List.

A large diversity of techniques were used to mine the flint. Open quarries, pits and networks of underground horizontal galleries can be found. Shafts between 10 and 15 m deep were sunk through the chalk, the galleries for the mining are radiating out.
