France’s oldest lighthouse (built 1584-1611), a Renaissance masterpiece 7km offshore in the Gironde, is a UNESCO World Heritage Site and still inhabited.
Key Takeaways

First Fresnel lens rotating system ever installed was fitted here in 1823 by Augustin-Jean Fresnel himself, making Cordouan a milestone in lighthouse optics history.
Engineer Joseph Teulere raised the tower in 1782-1789 and devised the first turning lighting dish in 1790, powered by Argand lamps run by a Dieppe watchmaker’s mechanism.
Automated in 2006 but remains inhabited; last state keepers left in 2012, replaced by SMIDDEST association members, making it France’s last inhabited lighthouse.
