You will sail along the coast to discover the remarkable Meschers caves, natural cavities carved into the chalk cliffs that loom over the Gironde estuary. Enlarged by man in the 19th century, they became troglodyte dwellings, some of which are still inhabited today. Punctuating the coastline of the Charente region with their poetic presence, the carrelets, fragile-looking huts on stilts fitted with a square fishing net, can be seen along the Saintonge coastline. The beautiful town of Talmont-sur-Gironde is to be found at the heart of the fortified city founded by Edward I, King of England and Duke of Aquitaine. The Sainte-Radegonde church, a jewel of Romanesque art, dating from the 12th century, looms majestically over the estuary.
