Cordouan lighthouse is an active lighthouse located 7 kilometres at sea, near the mouth of the Gironde estuary in France. At a height of 67.5 metres, it is the tenth-tallest "traditional lighthouse" in the world.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. Three stories were added in the 18th century.
It was listed as a historic monument in 1862, and recognized by UNESCO as a World Heritage Site in 2021.
