St Dwynwen

It may seem an odd and perilous place to build a church, but St Cwyfan's originally stood at the end of a peninsula between two bays, Porth Cwyfan and Porth China, as shown on John Speed's map of Anglesey from 1636. In the decades after this the sea slowly eroded the coast in the two bays enough that the peninsula was cut off, turning it into an island.

It is known that the present church on the island dates back to the 1400s. It is not known who built the church and why. It is however widely accepted that the church did replace an early church or chapel on the same site. The church on the island is small and has no electricity. Despite this services are still held in the church and it is very popular for weddings.

A typical little Welsh church, looking as though it has grown out of the bones of the hillside, with some striking medieval stained glass and seventeenth-century woodwork.
