"Lighthouses of Southwest England (Devon and Cornwall)". ![]() The main light currently flashes once every ten seconds, white with a red sector to the north-east the subsidiary white light has an isophase characteristic, two seconds on, two seconds off. The bell remained in use until 1994, when it was replaced by an electronic fog horn. Oversight of the lighthouse was passed from Trinity House to the Ministry of Defence in 1993. Following departure of the resident keepers, the light was monitored from the Trinity House fog signal station at nearby Penlee Point. In 1920 the lighthouse was converted to run automatically on acetylene gas. The following year, the light was made occulting (being eclipsed for three seconds every half minute). The bell sounded four strokes every minute in foggy weather. (The new bell had previously been in use at Start Point lighthouse, where a fog siren had replaced it two years earlier). In 1879 a larger (32 cwt) bell was installed, and the old bell was transferred to Gunfleet Lighthouse. īy 1867 a 7 cwt bell had been installed at the lighthouse to serve as a fog signal. Since 1854 a second white light has also been displayed, from a window lower down in the tower, indicating a channel between two hazards: the Draystone and the Knap it used a small, sixth-order dioptric lens. The lighthouse had been provided with a second-order catadioptric lens array by Henry Lepaute of Paris it showed a fixed red light with a white sector indicating an anchorage to the north-east (later the colours were reversed). Ī beacon was placed at the eastern end of the breakwater, consisting of a 6-foot (1.8 m) spherical cage on a 17-foot (5.2 m) pole the cage was designed as a refuge for six shipwrecked sailors. On completion, management of the light was transferred to Trinity House. The light became operational in June 1844 soon afterwards a horse-drawn omnibus was driven along the breakwater from end to end, with a full complement of passengers accompanied by a military band. Designed for the Admiralty by Walker & Burgess, construction of the granite tower began on 22 February 1841 and was completed on 9 November 1843 William Stuart was superintendent of the works. Plymouth Breakwater Lighthouse stands on the western tip of the breakwater. Whidbey continued to work on the breakwater and other engineering projects, including the breakwater's lighthouse, until retirement around 1830 the work was completed by Rennie's sons, George and Sir John. John Rennie died in 1821 his last work in connection with the breakwater was to draw up proposals for a lighthouse. Severe storm damage in 18 prompted a change in the profile and height. Napoleon was reported as commenting that the breakwater was a grand thing, as he passed by it on the way to exile on St. Carlos Rocks, and was sufficiently completed by 1814 to shelter ships of the line. It followed a line over Panther Rock, Shovel and St. The foundation stone was laid on Shovel Rock on August 8, 1812. A paper to the Royal Society suggests that Whidbey found many fossils as a result of the quarrying necessary to the breakwater. Nearly 4,000,000 (four million) tons of stone were quarried and transported, using about a dozen ships innovatively designed by the two engineers. This task required great engineering, organizational and political skills, as the many strictly technical challenges were complicated by the significant resources devoted to the project, from which various parties evidenced a desire for advantage. In 1811 came the order to begin construction Whidbey was appointed Acting Superintending Engineer. These plans may have been taken from ones made by George Matcham (1753 – 3 February 1833). Vincent commissioned John Rennie and Joseph Whidbey to plan a means of making Plymouth Bay a safe anchorage for the Channel Fleet. In 1806, as the Napoleonic Wars impended, Lord St. Around 4 million tons of rock were used in its construction in 1812 at the then-colossal cost of £1.5 million (equivalent to £106 million today). It lies in about 10 metres (33 ft) of water. ![]() ![]() ![]() It is 13 metres (43 ft) wide at the top and the base is 65 metres (213 ft). Plymouth Breakwater is a 1,560-metre (1,710 yd) stone breakwater protecting Plymouth Sound and the anchorages near Plymouth, Devon, England. Lighthouse Plymouth Breakwater Lighthouse
