Ramsey Island (Welsh: Ynys Dewi) is an island about 1km off St David's Head in Pembrokeshire on the northern side of St Brides Bay, in southwest Wales. It is 259ha in area. Ramsey means (in Old Norse) Hrafn's island. In Welsh the island is named after Saint David (Dewi Sant), the patron saint of Wales. It was the home of his confessor, Saint Justinian. The nearest large settlement is the city of St David's. Ramsey Island is less than 3.2 km (2 mi) long and its highest point is 136 metres (446 ft) above sea level at Carnllundain, and is listed as a HuMP. It is the fourth largest island in Wales, after Anglesey, Holy Island and Skomer, and is surrounded by a number of islets, tidal islands and rocks.
