In 1797, Trinity House granted a lease to Lieutenant Henry Smith and the architect Samuel Wyatt oversaw the building of the first lighthouse on Carn Bras, one of a group of rocky islets off Land's End. In 1875 Trinity House engineer Sir James Douglass installed a circular tower of grey granite. Longships Lighthouse was manned until 1967 but it was not until 1988 that the lighthouse was fully automated and run from Trinity House's Planning Centre in Harwich, Essex.
