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, with construction starting in 1584 and finishing in 1611. Designed by leading Paris architect Louis de Foix, the lighthouse is something of a Renaissance masterpiece, drawing inspiration from Roman mausoleums, and the palaces, cathedrals, and forts of the Renaissance. Three stories were added in the 18th century.
