Trefeiddan Moor

Clegyr Boia, or Clegyr Fwya, is a prehistoric site on the St David's peninsula, Pembrokeshire, Wales, 33 to 65 feet (10 to 20 m) above the surrounding area. It is about 1 mile (1.6 km) west of St Davids, and about 0.75 miles (1.21 km) east of the Pembrokeshire coast. The hilltop's rocky outcrop contains evidence of Neolithic and Iron Age settlements. The site's nearest water source was Ffynnon Lygaid, a 1 foot (0.30 m) deep pool, fed by a spring. Near the base of the outcrop's southern side, the pool is in a small hollow, measuring about 1 foot (0.30 m) by 8 inches (0.20 m). The site was excavated in 1902 by Sabine Baring-Gould, and by Audrey Williams, for the Ancient Monuments Inspectorate, in 1943. The outcrop became the stronghold of a 6th-century CE Irish pirate named Boia, after whom (with clegyr (English: crag)) it is now called.

St Davids Lifeboat Station (Welsh: Gorsaf Bad Achub Tyddewi) is located at St Justinian, overlooking Ramsey Sound to Ramsey Island, approximately 2.5 miles (4.0 km) west of the cathedral city of St Davids, in the county of Pembrokeshire, West Wales. A lifeboat was first placed at St Davids in 1869, by the Royal National Lifeboat Institution (RNLI). By 2010, it had been involved in saving over 360 lives at sea, having launched more than 420 times. The station currently operates a Tamar-class All-weather lifeboat (ALB), 16-26 Norah Wortley (ON 1306), on station since 2013, and the much smaller D-class (IB1) inshore lifeboat (ILB), Marian and Alan Clayton (D-840), on station since 2019.

St Davids Bishop's Palace (Welsh: Llys yr Esgob, Tyddewi) is a ruined medieval episcopal palace located adjacent to St Davids Cathedral in the city of St Davids, Pembrokeshire, one of the most important ecclesiastical sites in Wales. The site dates back to the 6th century, although the building that stands today dates largely from the late 13th and 14th centuries. The palace is under the management of Cadw, the historic environment service of the Welsh Government. It is open as a visitor attraction and an open-air theatre, and being part of the city's cathedral precinct, there are more than 300,000 visitors a year. It is a Grade I listed site.

St Davids or St David's (Welsh: Tyddewi, [tiː ˈðɛwi], lit. "David's house") is a cathedral city in Pembrokeshire, Wales. It lies on the River Alun and is part of the community of St Davids and the Cathedral Close. It is the resting place of Saint David, Wales's patron saint, and named after him. St Davids is the United Kingdom's smallest city by population (number of residents within the wider community was 1,751 in 2021) and urban area, but it is not the smallest city by local authority boundary area (which is the City of London). St Davids was given city status in the 12th century. This does not derive automatically, but in England and Wales was traditionally given to cathedral towns under practices laid down in the early 1540s, when Henry VIII founded dioceses. City status was lost in 1886, but restored in 1994 at the request of Queen Elizabeth II.

The Chapel of St Non is located on the coast near St David's in Pembrokeshire, West Wales. Held by tradition to mark the birthplace of St David, the ruin cannot be accurately dated but is unusual in that it is aligned north–south rather than the usual east–west. Near to the ruined chapel is a retreat, a modern chapel and a holy well. The site was protected in the 1950s and is now the responsibility of the Welsh Heritage organisation Cadw.

Penrhiw Priory was originally built as a vicarage in St Davids, Pembrokeshire, Wales, in 1884. The building was enlarged in the 1960s, serving for a time as a priory. In 2008 The Retreats Group Trust bought the building and commissioned Acanthus Holden Architects it undertake its conversion into a hotel. Then in 2012, Penrhiw Priory reopened as an eight-bedroom hotel restored along with Roch Castle and Twr y Felin Hotel, by the Griffiths Roch Foundation, which was set up in 2009 by international architect Keith Griffiths. It is a Grade-II listed building. The Priory's Garden Bedroom was used by the vicar who was placed here by the Church of England in 1882 to stem the migration to non-conformist chapels. The stables housed his horses and carriage which enabled him to visit parishioners to entice them back to the church.
