The Calf of Man and its offshore rocks have no fewer than four lighthouses: two lighthouses were built in 1818 under the Isle of Man and Calf of Man Lighthouses Act 1815 (55 Geo. 3. c. lxvii) by Robert Stevenson to warn mariners of the hazards of the Chicken Rock 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 Rock light. The Chicken Rock lighthouse was later rebuilt.Coakley, F.
