Iona Abbey is an abbey located on the island of Iona, just off the Isle of Mull on the West Coast of Scotland. It is one of the oldest Christian religious centres in Western Europe. The abbey was a focal point for the spread of Christianity throughout Scotland and marks the foundation of a monastic community by St. Columba, when Iona was part of the Kingdom of Dál Riata. Saint Aidan served as a monk at Iona, before helping to reestablish Christianity in Northumberland, on the island of Lindisfarne. Iona Abbey is the spiritual home of the Iona Community, an ecumenical Christian religious order, whose headquarters are in Glasgow. The Abbey remains a popular site of Christian pilgrimage today.
