Welcome to Bardsey Island (Ynys Enlli)
In the 6th or 7th century the obscure St Cadfan founded a monastery here, giving shelter to Celts fleeing the Saxon invaders, and medieval pilgrims followed in their wake. Three pilgrimages to Bardsey were said to be equivalent to one to Rome.
Most modern pilgrims to Bardsey are seabird-watchers; during the summer around 17,000 Manx shearwaters nest in burrows here, emerging at night. A colony of Atlantic grey seals lives here year-round; a pile of rocks by the harbour is a popular hang-out. Other sights include 6th-century carved stones, the remains of a 13th-century abbey tower and a candy-striped lighthouse.
