Point of Ayre, Isle of Man
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.
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).
