The Abbey, Iona

"Iona Abbey is located on the Isle of Iona, just off the Isle of Mull on the West Coast of Scotland. It is one of the oldest and most important 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."
