From the Wikipedia article
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.
