Nash Lighthouse was designed by James Walker, the Engineer-in-Chief to Trinity House, in 1832 to mark the sandbanks off the point at the entrance to the Bristol Channel. The decision to build it followed a public outcry after the passenger steamer FROLIC was wrecked with heavy loss of life in 1830.
Two circular towers were built each with massive walls and a stone gallery. The eastern, or high lighthouse being 37 metres high and the western or low lighthouse 25 metres high. Placed 302 metres apart they provided leading lights to indicate safe passage past the sandbanks. Today the low lighthouse has been abandoned and the high lighthouse has now been automated although this had the distinction of being the last manned lighthouse in Wales, the keepers leaving in August 2000.
Please obey the signs and do not pick any wild flowers.
