About La Roche Mengant Lighthouse
Completed in 1898, La Roche Mengant is a cylindrical stone tower standing 15 meters tall. It is painted black with a single red horizontal band. The structure features two galleries but does not have a lantern, with its light originating directly from the tower. Its focal height is 11 meters, and it emits a red flash every 12 seconds, with a geographic range of 10.7 nautical miles. This lighthouse is situated on an isolated rock in the Goulet de Brest, approximately 3.5 kilometers from Camaret-sur-Mer.
Why it matters: This lighthouse is essential for safe navigation through the Goulet de Brest, a busy strait leading to the port of Brest. Its unique lighting characteristic provides important sector guidance, warning mariners of the rock it marks and directing them through the safest channels.
