The Eddystone Lighthouse is a lighthouse on the Eddystone Rocks, 9 statute miles (14 km) south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea[3] and are composed of Precambrian gneiss.[4]

The current structure is the fourth to be built on the site. The first lighthouse (Winstanley's) was swept away in a powerful storm, killing its architect and five other men in the process. The second (Rudyard's) stood for fifty years before it burned down. The third (Smeaton's) is renowned because of its influence on lighthouse design and its importance in the development of concrete for building; its upper portions were re-erected in Plymouth as a monument.[5] The first lighthouse, completed in 1699, was the world's first open ocean lighthouse, although the Cordouan Lighthouse off the western French coast preceded it as the first offshore lighthouse.[6]
