Below are maps (c1750-80) of the village of Port de Pile. It stands on the south bank of the River Creuse and about 10k north-west of Descartes, and surrounding communities just over the border in the Vienne department. The village of Lasselle which is also shown is now called, La-Celle-Saint-Avant. The maps themselves come from the wonderful on-line collection of maps, images and documents at the French Ministry of Culture’s web site.
