Neolithic flint mines of Spiennes

The Neolithic flint mines of Spiennes, located in Belgium, are ancient archaeological sites dating back around 4,000 to 3,500 BCE. These sites feature extensive underground tunnels and open-air extraction areas where early communities mined flint, a durable stone used for making tools like arrowheads and blades. The mines reveal sophisticated mining techniques and a well-organized effort to gather resources necessary for daily life and trade. Recognized as one of the largest Neolithic flint mining complexes in Europe, they provide valuable insight into early technological skills and social organization.
