United Kingdom:
Like Ireland, the United Kingdom has several pilgrimage sites tied to ancient Christianity or Celtic Christianity, predating the arrival of St. Augustine and the founding of Canterbury Cathedral. These include:
- St. Bertram of Ilam, England
- St. Cafdan in Wales;
- St. Columba in Iona, Scotland
The ancient ones associated with Roman Christianity include:
- Abbey of St. Edmund the Martyr.
