The Nash Point Lighthouse is a Grade II listed building, dating from 1831-32. There are two lights, a high light and a low light, located at a distance of around 300 metres from one another.[3] The lighthouse was designed by James Walker, the chief engineer for Trinity House. Its construction is said to have been spurred by the wreck of The Frolic on the Nash Sands in March 1831, [8] which resulted in over 50 deaths, including that of Lt-Col N McLeod.[9] The ship was on its way from Bristol to Haverfordwest.[10] First lit in 1832, the lighthouse was electrified in 1968. Nash Point Lighthouse became the last manned lighthouse in Wales, and was automated in 1998. The lighthouse is now open to visitors, and is often used as a wedding venue; Trinity House provides public tours. The fog signal, no longer needed by ships, is sounded on the first Saturday and third Sunday of each month as an additional attraction to visitors.[11]
