Aerial View of Cordouan Lighthouse off Royan

Cordouan is a lighthouse located 7 km at sea, geographically located near the mouth of the Gironde estuary in Prancis.

The Tour de Cordouan, the 'Patriarch of Lighthouses', is by far the oldest lighthouse in France. It was designed by leading Paris architect Louis de Foix, and is something of a Renaissance masterpiece, an amalgam of royal palace, cathedral and fort. Started in 1584 and finished in 1611, it still stands today.
