It is the location of the Les Hanois Lighthouse operated by Trinity House which was built in 1862 from Cornish granite, to a design by James Walker, using a novel dovetail system to lock each stone with the vertically and horizontally adjacent stones.[3] It was built in the hope of reducing the number of ships being lost on the reef on the west coast of Guernsey; it undoubtedly saved a number of ships. However, the wrecks continued, the last disaster being the MV Prosperity in 1974, a freighter lost with all hands on La Conchée reef.[4]
