Neolithic flint mines of Spiennes

The Neolithic flint mines of Spiennes, located near Mons in Belgium, are among the largest and earliest known flint mining sites in north-western Europe. Active between 4300 BCE and 2200 BCE, these mines demonstrate remarkable technological innovation in extracting and processing flint. The site covers approximately 100 hectares and features numerous vertical mine shafts leading to an intricate network of underground caverns. Neolithic settlers used flint picks to extract large slabs of flint, which were then fashioned into axes and other tools for various uses such as forest clearance and woodworking. The site showcases the transition from opencast to underground mining techniques, underscoring a significant period of human technological and cultural development. Recognized for its historical importance, the site was declared a UNESCO World Heritage Site in 2000.
