The Pendeen Lighthouse is a lighthouse on the Cornish coast . It stands eleven kilometers northwest of Penzance on the cliff coast of Pendeen Watch. The height of the beacon is 59 m above mean high tide .
description
The lighthouse is 17 m high. It consists of quarry stone clad with concrete. The tower consists of two floors with one room each. Above is the lamp house with a gallery running around it. The lighthouse has a one-story extension with a flat roof and a smaller building with a foghorn. The buildings are painted white.
Signals
The white beacon can be seen 16 nm (30 km) away. It is generated with a 35 W mercury vapor lamp of the MBI type. A Fresnel lens system rotates around the lamp so that observers see four flashes every 15 seconds ( identifier Fl (4) 15s). The original lens apparatus is still used. It weighs 2.5 t and floats on 750 kg of mercury , which makes it easy to turn.
A fog horn was permanently decommissioned on May 14, 2014. If necessary, there was a signal every 20 seconds, which was still audible on Cape Cornwall, five kilometers away .
history
The lighthouse was built from January 1899 to secure shipping between Cape Cornwall and St. Ives Bay. The client was the operator of the lighthouses in England and Wales, Trinity House . The designs are from Thomas Matthews , Trinity House's chief engineer. Extensive earthworks were required for the construction because the summit of Cape Pendeen Watch had to be terraced . On September 26th, a five-flame Argand oil lamp was put into operation. The beacon has been electric since 1926.
Until 1995, beacon guards responsible for the operation, the lighthouse was automated. Today it is controlled via a telemetry connection to the Trinity House Operational Control Center in Harwich . The annex, which originally provided accommodation for three lighthouse keepers with their families, has been converted into holiday apartments.
