St Cwyfan's Church
Eglwys Cwyfan
A 12th-century chapel on a tidal islet known as the “church in the sea,” one of Anglesey’s most photogenic scenes.
St Cwyfan’s Church stands in Porth Cwyfan Bay, south of Aberffraw. Built in the 12th century, it originally stood on a headland, but coastal erosion turned it into a tidal islet surrounded by a stone wall, which is completely cut off by the sea at high tide. The church has a plain exterior; it hosts services and music events in summer, but its interior is usually closed, so visitors mainly admire the exterior and the bay. At low tide you can walk to the island along a causeway, but check the tide times first. Park by the road and walk about 10 minutes; it can be combined with Aberffraw Beach and the Barclodiad y Gawres burial chamber.
Opening hours
Exterior visible all day; island accessible at low tide
