Chicken Rock (Manx: Carrick ny Kirkey), part of Rushen parish, is the southernmost island administered by the Isle of Man. It lies southwest of the Calf of Man, 4.5 kilometres (2.8 mi) off Spanish Head on the Manx mainland. There is a lighthouse on the island. The 44 metres (144 ft) lighthouse is constructed of tapered granite and was designed by David and Thomas Stevenson, after the lights on the Calf of Man were insufficient at warning ships away. Construction finished in December 1874, with the first official lighting day taking place on 1 January, 1875.
A fire heavily damaged the interior of the lighthouse on 23 December, 1960. The light became automated in 1961. The lighthouse is owned and maintained by the Northern Lighthouse Board.
