Le Grand-Pressigny

A major Chalcolithic flint mining and production centre in the Indre-et-Loire department of central France, active around 3000 BC during the Final Neolithic. The site produced distinctive caramel-coloured flint of exceptional quality, from which master carvers struck large blades up to 40 cm long that were distributed across Europe to the Alps, Brittany, and Holland. The characteristic products known as livres de beurre (butter loaves) are elongated cores from which long flakes were struck. The site is now home to a prehistory museum housing over 450 archaeological items.
