The Longships Lighthouse stands on Carn Bras, the highest of the Longships islets which rises 39 feet (12 m) above high water level. The original tower was built in 1795 to the design of Trinity House architect Samuel Wyatt. The lantern was 79 feet (24 m) above sea level but very high seas obscured its light.[1]
In 1869 Trinity House began constructing a replacement.[2] The building of the present granite tower used much of the equipment that had previously been used in the construction of the Wolf Rock Lighthouse.[2] The tower was first lit in December 1873 having cost £43,870 to build.[2] Even after these improvements, the S.S. Bluejacket was wrecked on rocks near the lighthouse on a clear night in 1898, nearly demolishing the lighthouse in the process.
Since 1988, the lighthouse has been unmanned. Its light has a range of 11 nautical miles (20 km; 13 mi), and gives one long five-second flash every ten seconds. The flashes are white when seen from seaward, but red sectors show if a vessel strays too close to either Cape Cornwall to the north or Gwennap Head to the south-southeast. A fog signal sounds every ten seconds.
