Vieille carte de Bretagne

An old map of Brittany, which situates the Bretons de Bourgneuf salt marshes in Retz, and which includes the islands of Bouin and Noirmoutier in Brittany, because its parishes of the Brito-Poitevinnes marches were advantaged to Brittany, because they depended on the diocese of Nantes and not on that of Luçon.
