Church Bay, Anglesey

Clegir Mawr is a Site of Special Scientific Interest (SSSI) in the community of Cylch-y-Garn in the north-west of the island of Anglesey, Wales. It is a stony coastal headland with an area just under 10 hectares (25 acres) and has been designated principally because of the occurrence of the spotted rock-rose (Tuberaria guttata) which is a nationally rare plant and also the county flower of Anglesey.

Carreglwyd is a Georgian country house, northwest of Llanfaethlu, Anglesey, Wales, which became a Grade II* listed building in 1952. Its gardens and parkland are listed as Grade II* on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.The earliest mention of the estate is in 1544, when William Griffiths, the Rector of Llanfaethlu, whose ancestors were the Griffiths family of Penrhyn, bought a house named "Ty'n y Pant". His grandson, the Chancellor William Griffiths, oversaw the building of a new house on the site in 1634. Another William Griffiths, the Chancellor's grandson, made further alterations in the late 17th century and early 18th century, the oldest of which remains in the southwest side of the house. The fine hall of the house dates to this period. During the ownership of Holland Griffiths (1756-1839) in the late 18th and early 19th century, further remodelling of the estate was conducted, during which time the dining room, sitting room and library were given a major renovation. The interior was updated in the 1980s.

Rhydwyn (; Rhyd-Wyn) is a village in the community of Cylch-y-Garn, in the north west of Anglesey, Wales. Rhydwyn is named after a little stream that once crossed the centre of the village. "Rhyd" meaning Ford and "Wyn" white. It now runs through a culvert under the road.

Llanfair-yng-Nghornwy (, also spelt Llanfairynghornwy) is a village in Anglesey, in north-west Wales.

Today it is part of the community of Cylch-y-Garn.

Cylch-y-Garn is a community in Anglesey, Wales, located on the north west coast of the county, 9.0 miles (14.5 km) west of Amlwch, 12.5 miles (20.1 km) north east of Holyhead and 15.0 miles (24.1 km) north west of Llangefni. It includes the villages of Llanfair-yng-Nghornwy, Llanrhyddlad and Rhydwyn, plus Llanrhwydrys, Caerau and Cemlyn. the north west tip of the island at Carmel Head, and the offshore islands of the Skerries and West Mouse. At the 2001 census the community had a population of 675, increasing to 758 at the 2011 census. St Mary's Church at Llanfair-yng-Nghornwy is of early medieval origin and has a chancel arch dating from the 11th or 12th century. It is mentioned in the Norwich Taxation of 1254. The chancel was lengthened in the 15th century, and a south chapel added in the 16th. The west tower was added in the 17th century, and the church was restored in 1847, and again in both 1860 and the 1930s. Cadw considers it to be "a fine rural parish church, incorporating significant early medieval fabric", and claims that it is "of special interest, therefore, both for its early origins and for the quality of its later detail," and it is Grade I listed. Saint Rhwydrus's Church, near Cemlyn Bay, was also built in the 12th century, but only the nave survives, although of particular interest is a doorway to the nave dating from that period. It is Grade II* listed, as is Caerau, a late 17th-century house in Llanfair-yng-Nghornwy which contains original panelling. Cemlyn Bay is located in the north east of the community, and is owned by the National Trust. It is the site of a nature reserve managed by the North Wales Wildlife Trust, which includes a lagoon separated from the sea by Esgair Gemlyn, a shingle ridge formed by longshore drift. Islands in the lagoon provide nesting sites for common and Arctic terns, and for one of the United Kingdom's largest breeding populations of Sandwich terns. Offshore, the Skerries lie north west of Carmel Head at the end of a submerged reef which lies directly in the path of shipping traveling between Liverpool and Ireland. In 1714 Queen Anne granted William Trench the right to build a lighthouse on the rocks, and to levy dues on passing ships. The light came into operation in 1717, but ship owners evaded payment, and Trench died in 1729, heavily in debt. The lighthouse was eventually bought by Trinity House in 1841, the last privately owned lighthouse in the British Isles purchased by the organisation. The coal grate was replaced by an oil lamp in 1804, and converted to electric operation in 1927. Since 1987 it has been unmanned, and controlled automatically from Harwich.

Carmel Head (Welsh: Trwyn y Gadair) is a prominent coastal headland on the northwest tip of the island of Anglesey. It is a designated SSSI because of its geological interest for the Carmel Head Thrust fault where Precambrian rocks have been pushed over younger Ordovician rocks creating the Carmel Head thrust. Rock exposures along the cliffs of Carmel Head include Precambrian gneisses, which are almost certainly the oldest rocks in Wales. In the summer months the Anglesey Coastal Path passes over Carmel Head on a permissive path but in winter the path is closed to all for pheasant shooting. Most of the land on the head, which peaks at 81 metres above sea level, is owned and managed by the National Trust.

St Mary's Church, Llanfair-yng-Nghornwy is a medieval parish church in the north-west of Anglesey, north Wales. The date of foundation of the church, which is in the village of Llanfair-yng-Nghornwy, is unknown, but the oldest parts date from the 11th or 12th century. It has twice been enlarged: in the 15th century, when the chancel was rebuilt, and in the 16th century, when a chapel was added to the south of the chancel, separated by three arches. The tower at the west end is from the 17th century. A south porch of unknown date has been converted into a vestry, and the church is now entered through the tower. St Mary's is a Grade I listed building, a national designation given to buildings of "exceptional, usually national, interest", in particular because it is regarded as "a fine rural parish church, incorporating significant early Medieval fabric". Writers in the 19th century commented on the "lofty square tower", the "very good" east window, and the "many elegant monuments"; the clergyman and antiquarian Harry Longueville Jones called St Mary's "one of the best specimens of an old parish church in the island". In the 21st century, one writer has noted the "impressive lychgate" and a guide to the buildings of the region calls it "the most important church in north west Anglesey". The church is still used for worship by the Church in Wales, one of nine in a combined parish, although as of 2013 there has not been an incumbent priest since September 2009. People associated with the church include James Williams, a 19th-century rector who was awarded a gold medal for his efforts to save lives at sea, and his great-grandson, the artist Sir Kyffin Williams. Both are buried in the churchyard.
