Le Grand-Pressigny
From Wikipedia, the free encyclopedia
Le Grand-Pressigny is a commune of the Indre-et-Loire département in France.
Grand Pressigny is the name of 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.
