Île Madame
Île Madame is an island in the River Charente estuary on the Atlantic coast of France joined to the mainland by a causeway. The island has an area of four square miles and is unpopulated.
Hundreds of Catholic priests were held prisoner on the island during anti-clerical persecution in 1794. A total of 254 died before the survivors were allowed to leave.
The priests who were held prisoner and those who died on the island are commemorated during a pilgrimage there each August.
