Construction and dimensions
An application to build the Lighthouse was made in March 1827 on behalf of traders in Carmarthen Bay. It was commissioned by Trinity House and built by Joseph Nelson at a cost of £4,460. The light was first lit in 1829.
The Lighthouse is a squat, round, brick-lined limestone tower of 17.07m (56ft), with walls 0.91m (3ft) thick at the base and 2 ft 6 in (0.76 m) thick at the top. The light stands 64m (210ft) above high-water mark. It acts in conjunction with the Lundy North lighthouse to the south, and has a range of 13 nautical miles (24 km). Lundy
Lantern and lamp
The Lighthouse was converted to automatic operations in 1929. It was the last Trinity House lighthouse to be powered by gas, eventually being converted to electricity in 1997.
The light was intended to help coastal traffic trading limestone and coal to mid and north Wales but the light also helped long-distance and north American traffic identify the Bristol Channel and avoid confusion with the English Channel.
The lighthouse keepers' cottages, that flank the Lighthouse, are two-storey, with hipped roofs, octagonal chimneys, and a one-storey linking corridor. This forms a ‘U’-shape, with the Lighthouse at the centre of the south side, and enclosed gardens to the north. The cottages were built around 1868-70 by T. C. Harvey, C.E.
