Trinity House
The Needles Lighthouse is an active 19th century lighthouse on the outermost of the chalk rocks at The Needles on the Isle of Wight in the United Kingdom, near sea level. Designed by James Walker, for Trinity House at a cost of £20,000. It was completed in 1859 from granite blocks, and stands 33.25 metres (109.1 ft) high and is a circular tower with straight sides.
It replaced an earlier light tower on top of a cliff overhanging Scratchell's Bay, which was first lit on 29 September 1786. Its height of 144m above sea level meant it was often obscured by fog and sea mists.
In 1987 a helipad was added to the top of the lighthouse, and it became fully automated when the last keepers left on 8 December 1994. One of the last three remaining manned rock lighthouses in England and Wales, before automation it was staffed by a three-man crew operating a 24-hour watch, serving one month on / one month off, living in rudimentary conditions in three levels below the light.
Due to the condition of the chalk strata on which the lighthouse was built, in April 2010 a £500,000 underpinning project was announced, designed to stop the lighthouse falling into the sea. Over a 12-week period from early June, civil marine contractors Nuttall John Martin excavated a trench around the base of the lighthouse, to install a ring of stabilising posts, reinforced with concrete.
