Neolithic Flint Mines of Spiennes

The Neolithic Flint Mines of Spiennes, located southeast of Mons, Belgium, represent one of north-western Europe's largest and earliest Neolithic flint extraction sites, active from 4300 to 2200 BC. These underground mines yielded high-quality flint used for tools and weapons across Neolithic communities. The site showcases remarkable diversity in extraction techniques, including shafts, galleries, and wooden support structures. Inscribed on UNESCO's World Heritage List in 2000, the mines provide exceptional insight into Neolithic mining technology and social organization.[1][2]
