History
The original 1868 lighthouse was a cast iron tower, 190 feet (58 m) tall, tapering to a mere 13 feet (4 m) in diameter at the top. It was a twin to Amédée lighthouse. The tower was constructed from elements which were built by Rigolet in Paris. The tower was constructed for the first time in 1866 on Champ de Mars, Paris, for the Exposition Universelle of 1867. It was then disassembled and the parts were transferred to Brehat. The light was first lit on December 15, 1868 during the construction, with a characteristic of white flash every 4s. Actual construction was only completed on August 1869. On June 18, 1903 the fuel was changed to petroleum. The lighthouse was destroyed during in 1944 during World War II by German troops. In April 1950 a temporary light was mounted on a 17 metres (56 ft) pylon. In April 1952 a light was mounted on the tower under construction. The construction was completed on June 19, 1954 and the light too the current characteristic. In July 1971 the light was electrified, where electricity comes from two wind turbines on towers of concrete and a generator. In October 2000 the lighthouse is automated.
