The Pointe du Grouin du Cou Lighthouse (sometimes called the La Tranche-sur-Mer Lighthouse) is a French lighthouse, located on the eponymous point in the southern part of the Vendée department; it guards the entrance to the Pertuis Breton on the Île de Ré, on the west side of La Tranche-sur-Mer. The lighthouse, constructed in 1953 to a design by Maurice Durand, replaces an earlier tower that was destroyed by retreating German troops during World War II.[1]

History
The first lighthouse on the site was lit on 1 July 1831; it was a small cylindrical tourelle encased in masonry, and showed a fixed white light. A short tower, it stood only Script error: No such module "convert". tall, and was intended to warn ships' captains off of the treacherous limestone rocks that could be found in the area. A taller light, Script error: No such module "convert". tall, was installed in May 1867, and also showed a fixed white light. This was changed in 1893 to a light which flashed every five seconds, and which showed white and red sectors. In 1906 the signal was converted to a mercury-vapor lamp,[4] and in 1931 it received a supplementary green sector.[5] The lighthouse was powered by various means at various points in its career, notably vegetable oil (1831), mineral oil (around 1875), gas (1906) and finally electricity (1953).[4]
The lighthouse at the point was completely demolished on the night of 24 July 1944 by German soldiers. A temporary wooden pylon was erected soon after, being lit on 10 October of the following year;[4] the old lighthouse was not permanently replaced, however, until 1953. On 25 April of that year the new tower showed its light, an electric signal,[4] for the first time; it was tended by a keeper until 1985, when it was automated.[5] Today the lighthouse is controlled automatically from Les Sables-d'Olonne; its property is still owned by the government, and is off-limits to visitors.[3]
