The Point of Ayre Lighthouse is an active 19th century lighthouse, sited at the Point of Ayre at the north-eastern end of the Isle of Man. It was designed and built by Robert Stevenson, grandfather of prolific writer and novelist Robert Louis Stevenson, and was first lit in 1818, making it the oldest operational lighthouse on the island.[1][2]

Description

The lighthouse still retains its original 1st order Fresnel lens from 1890, which was supplied by Barbier, Benard, et Turenne of Paris. With a focal height or elevation of 32 metres (105 ft) above sea level, the light from the 30 metres (98 ft) tower has a nominal range of around 19 nautical miles (35 km). Its light characteristic is made up of a pattern of four flashes of white light every twenty seconds. The tower has a distinctive daymark of two red bands, the light can be seen clearly from across the water in south-west Scotland.[1]

Owing to the continuous accumulation of shingle and gravel deposited by the strong currents, a smaller light commonly referred to as a 'winkie' had to be built 750 feet (230 m) to the seaward side of the main tower in 1899. This was then repositioned a further 250 feet (76 m) in the same direction and for the same reasons in 1950. The 'winkie' light was discontinued on 7 April 2010.[1][2]

The lighthouse buildings and land have been in private ownership since 1993 when the light was fully automated. The light continues to be maintained by the Northern Lighthouse Board based in Edinburgh. In August, 2005, the fog signal at the lighthouse was de-commissioned owing to the assumed reliance and availability of GPS and modern shipping guidance systems.[2]
