Le Grand-Pressigny

Le Grand-Pressigny is a commune in the Indre-et-Loire department in central France.

There is a Chalcolithic flint mine located in the commune. It produced an unusual caramel-coloured stone which appears to have been highly prized across Europe with examples found in the Pyrenees, the Netherlands and Switzerland. Blocks of flint and unfinished blanks were traded, as well as finished tools.
