History and interest
- Rhoscolyn was formerly known as Llanwenfaen (the church of St. Gwenfaen). The name is said to derive from ‘The Moor (Rhos) of the Column (colyn)’, referring to a pillar erected by the Romans to mark their boundaries.
- St Gwenfaen’s Church was founded in 630AD and has a medieval doorway and 15th century font.
- Legend says that St Gwenfaen was chased from her cell by druids, and that she escaped by climbing the rock stack off Rhoscolyn Head. The tide came in and she was carried away by angels. Saints Bay takes its name from this incident.
- Also at Rhoscolyn Head there are rock arches called Bwa Du the black arch, and Bwa Gwyn, the white arch.
- St Gwenfaen’s Well, surrounded by medieval stone steps and seating, was used by pilgrims during the Middle Ages who believed in the water’s healing powers.
- Porth-y-Corwgl is of regional importance as one of the best-exposed geological faults on Anglesey.
