context_page_description: Ramsey Island is an island about 1 kilometre off St David's Head in Pembrokeshire on the northern side of St Brides Bay, in southwest Wales. It is 259 hectares in area. Ramsey means Hrafn's island.
  In Welsh the island is named after Saint David, 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 long and its highest point is 136 metres 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.
context_section_description: The waters around the island have significant tidal effects, and tidal waterfalls occur between The Bitches. The asymmetrical underwater flow can be 3.8 m/s (12.5 ft/s) northward (flood) and 1.9 m/s (6.2 ft/s) southward (ebb), with some turbulence. 
  The sound reaches some 66 metres (217 feet) deep, although a tidal island called Horse Rock protrudes from the water at low tide; the name of the rock was recorded as early as 1583, on an Elizabethan map.
  A 400 kW tidal power turbine project was planned from 2014 and the first turbine of three was installed in December 2015.
  Ramsey Island is surrounded by a number of smaller islands, islets and rock clusters, including:
  Bancyn-ffald
  The Bitches
  The Bishops and Clerks group, including:
  Carreg Rhoson and Maen Rhoson
  Carreg-trai
  Cribog
  Daufraich and Maen Daufraich
  Emsger or South Bishop (37 metres, 121 feet)
  Llechau-isaf and Llechau-uchaf
  Moelyn
  North Bishop (44 metres, 144 feet)
  Carreg-gwylan
  Meini Duon (Black Rocks) is the name given to three sea rocks approximately two-thirds of a mile south of Ramsey Island, not far from the Bishops and Clerks. They are made of acid intrusive rock, and are the furthest south-west of the group of small islets and rocks off this coast.
  Trwynmynachdy
  Ynys Bery (Falcon Island) (71 metres, 233 feet)
  Ynys Cantwr (Precentor's Island; formerly owned by the precentors of  St David's.), a small tidal island south of Ramsey Island. Its highest point is 54 metres.
  Ynys Eilun (5 acres (2.0 ha), length 850 feet (0.26 km)) and Pont yr Eilun are two islets about a quarter of a mile east of Ynys Bery. Visiting the island is not easy because of its difficult landing. The surrounding waters are swept by a northeast current caused by Ynys Eilun itself.
  Ynys Gwelltog (Grassy Island; 56 metres, 184 feet), a tidal island, in the past considered suitable for pasturing two sheep.
