The Eddystone Lighthouse is a lighthouse that is located on the dangerous Eddystone Rocks, 9 statute miles (14 km) south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea and are composed of Precambrian gneiss.
This tower was the third lighthouse to be built on the Eddystone and marked a major step forward in the design of such structures.
In 1877 it was resolved to build a fourth replacement lighthouse, following reports that erosion to the rocks under Smeaton's tower was causing it to shake from side to side whenever large waves hit. During construction of the new lighthouse, the Town Council of Plymouth petitioned for Smeaton's tower to be dismantled and rebuilt on Plymouth Hoe, in lieu of a Trinity House daymark which stood there. Trinity House consented to the removal and delivery of the lantern and the upper four rooms of the tower, the cost of labour to be borne by Plymouth Council. While the new tower was being built the old lighthouse remained operational, up until 3 February 1882 (after which a temporary fixed light was shown from the top of the new tower).
The upper part of Smeaton's lighthouse was subsequently rebuilt, as planned, on top of a replica granite frustum on Plymouth Hoe: preserved 'as a monument to Smeaton's genius, and in commemoration of one of the most successful, useful and instructive works ever accomplished in civil engineering'. The rebuilding was funded by public subscription. It remains in place today and, as 'Smeaton's Tower', is open to the public as a tourist attraction.en.wikipedia.org
My own great grandfather was a keeper at Smeeton's Tower when it was out at Eddystone.
