The Lizard Lighthouse is a lighthouse at Lizard Point in Cornwall, England, built to guide vessels passing through the English Channel. It was often the welcoming beacon to persons returning to England, where on a clear night, the reflected light could be seen 100 mi (160 km) away.[2][3]


A light was first exhibited here in 1619,[4] built thanks to the efforts of Sir Christopher Dimaline but it was extinguished and the tower demolished in 1630 because of difficulties in raising funds for its operation and maintenance.

The current lighthouse, consisting of two towers with cottages between them, was built in 1751 by the landowner Thomas Fonnereau; each tower was topped by a coal-fired brazier.[5] Trinity House took responsibility for the installation in 1771. In 1812 the coal burners on each tower were replaced with Argand lamps and reflectors.[6]

In 1874 the site was significantly changed by the building of an engine room to provide electric power, not only for the lights but also for a fog siren, added in 1877 (this sounded through a 15-foot (4.6 m) horizontal horn which was installed on the roof of the engine house and could be moved depending on the prevailing wind direction).[7] The engine room was equipped with three 10hp caloric engines by A & F Brown of New York,[7] driving six Siemens dynamo-electric machines, which in turn powered an arc lamp in each tower.[5] At the same time a pair of medium-sized (third-order) fixed catadioptric optics were installed, one on each tower, designed by John Hopkinson of Chance Brothers.[8] The new electric lights were first lit on 29 March 1878. In 1885 the Siemens dynamos were replaced by a pair of more powerful de Méritens magneto-electric generators.

In 1903 there were further changes when a large four-panel rotating optic was installed in the eastern tower and both the lantern and light on the western tower were removed. In 1908 a new pair of sirens were installed (sounding out to sea through twin 'trumpets' on the roof of the engine house) and a trio of Hornsby oil engines replaced the caloric engines .[7] Soon afterwards an underwater bell was set up two miles south of the Lizard, operated by an electric striker controlled from the lighthouse via a submarine cable.

A carbon arc lamp continued to provide the light source until it was superseded in 1926 by an electric filament lamp.[9] The engines and magneto generators continued in daily use until 1950, when the lighthouse was connected to mains electricity. In that year four Gardner diesel engines were installed, three to run compressors for the fog signal, the other linked to a pair of generators for use in the event of a mains power failure.[7] In March 1954 the lighthouse keeper and assistants were able to put out a fire that was started in the exhaust pits of the engines providing the electric power.[10]

In 1998, Lizard Lighthouse was automated and demanned.[5] The fog horn was decommissioned in 1998 and replaced with an automatic electronic fog signal; at the time it was the last compressed-air fog signal still in use in the United Kingdom. The machinery is still in place and it is still occasionally sounded to mark special occasions.[11] The rotating optic continues in use to this day.[7]

Lighthouse Heritage Centre[edit]

Opened in 2009 with a grant from the Heritage Lottery Fund,[12] the Lizard Lighthouse Heritage Centre is located in the lighthouse engine room, which still features some of the original engines. Interactive exhibits and displays focus on the history of the lighthouse, the life of a lighthouse keeper, and the role of lighthouses in sea safety. Currently, the buildings around the site are being used as holiday cottages. [13]


One of the lighthouse's former generators is now in the collection of Thinktank, Birmingham Science Museum;[14] it carries a plate marked:[14]

L'Electricite magneto - Electrique No.21b. A de meritens, 44 Rue Bournalt Paris. Dte S.G.D.G. on France at L'Etranger

The other is still in situ in the engine house.[7]
