Cordouan lighthouse's origins

The Cordouan lighthouse, standing 68 meters tall, has a long and layered history. Its construction began in 1584 under Henri IV, with Louis de Foix overseeing the original tower, which was completed in 1611 after delays caused by religious conflicts and high costs.

Construction delays and completion

The original tower was built to a height of 37 meters above the highest tides, but it was not finished until 1611—27 years after the project began. Louis de Foix, who had signed the contract, did not live to see its completion, as he died before the work was done.

18th-century expansion

In the 18th century, as maritime navigation improved, the original light was considered too low for safe passage. Joseph Teulère was tasked with raising the lighthouse, adding 20 meters to its height between 1788 and 1789. The new structure included a stone cylinder placed on the chapel’s dome and a new lantern with parabolic reflectors.

Architectural styles and UNESCO recognition

The lighthouse combines Renaissance and Louis XVI styles. The lower part, including the foundation and chapel, dates back to the Renaissance, while the upper section, added by Teulère, reflects neoclassical design. UNESCO notes the clear transition between the two styles and the integration of the additions into the original structure.

Location and significance

Located on a rocky plateau at the mouth of the Gironde estuary, the lighthouse is visible from 7 km out at sea under certain weather conditions. It remains the oldest active lighthouse in France and was added to the UNESCO World Heritage list in 2021 for its historical and maritime significance.

Cordouan's legacy

Known as the "king of lighthouses" and the "Versailles of the seas," Cordouan is both a royal monument and a functional maritime aid. Visitors can climb 301 steps to reach the top, and the structure rises on eight levels, as noted by UNESCO.
