Trearddur
village and community on Holy Island, in Anglesey, Wales, UK
Trearddur or Trearddur Bay (Welsh: Bae Trearddur) is a village, seaside resort and community south of Holyhead on the west coast of Holy Island off the north-west coast of Anglesey in Wales. The community includes the small settlements of Penrhosfeilw and Goferydd and the Refail Farm estate.
Name
Historically the bay on which the village sits was known as Porth y Capel (Welsh: bay of the chapel) and the nearby dunes as Towyn y Capel (dune of the chapel). The village name is recorded variously as Treffyarddr, Tre Iarthur and Trefarthur with Trearddur first recorded in 1749. All versions signify the settlement of Iarddur, a key figure in the Middle Ages.
History
At the centre of the beach lies an ancient burial ground known by the old names and which was excavated in 2003.
At the 2001 census, the community had a population of 1,858, reducing to 1,686 at the 2011 census.
Like many places on the Welsh coast, Trearddur is somewhat anglicised, with 44% of the population born in England.
Amenities
There is one general shop in the centre of the village, along with a garage, two golf courses (one 18-hole (Holyhead Golf Club) and one small 9-hole) and two hotels including a large hotel, Trearddur Bay Hotel, which overlooks the beach. The other is the Beach Motel.
