The village lies about south of Royan, on a small promontory which dominates the Gironde Estuary. It appears to be ‘perched’ on this rocky outcrop, in the way that it occupies every square millimetre of space. Tiny beaches can be found at the base of the fortifications, which mostly are sheer from the sea. Inland there is marshy country and a small waterway runs alongside the south wall of the village.
The enclosed and fortified village was founded around the church in 1284, according to the plans of the ancient bastides, on the orders of Edward I of England. During the Hundred Year War which divided England and France, Talmont became a strategic stake. In 1652, the village was destroyed by the Spanish.
