Calf of Man lighthouse

The Calf of Man currently boasts the world's highest density of lighthouses: two lighthouses were built in 1818 by Robert Stevenson to warn mariners of the hazards of the Chicken Rocks off the south end of the Calf. These were replaced in 1875 by a lighthouse built on the Chicken Rocks themselves. In 1968, a third lighthouse was built on the Calf after a severe fire destroyed the Chicken Rocks light. The Chicken Rocks lighthouse was later rebuilt.
