Origin 563

A small island off the west coast of Mull from which Irish monks evangelised much of Scotland and northern England, still in continuous religious use. The medieval Benedictine abbey, restored in the twentieth century, is the base of the Iona Community, an ecumenical dispersed community founded in 1938 which combines worship with social and political commitment, so the island functions as a working retreat centre rather than a monument. The crossing takes two ferries and the accommodation is limited, which regulates numbers more effectively than any rule would.

Type of Site Detail
Viking raids struck the island repeatedly in the early ninth century, and the raid of 806 alone is recorded as killing sixty eight monks. The community eventually judged the island indefensible and moved Columba's relics and its own head house to Kells in Ireland for safety, which is why the great illuminated gospel book associated with Columba's foundation carries the Kells name rather than Iona's. 2

The Small Island That Converted the North

Iona, a small island off the coast of Mull in the Scottish Hebrides, was the base from which Irish monasticism carried Christianity through much of Scotland and northern England, and it has been in religious use for close to fifteen centuries.

Columba's foundation

According to tradition Columba, an Irish monk and prince, came to Iona in 563 and founded a monastery that became one of the most influential in the insular Christian world. From Iona monks evangelised the Picts and, later, from its daughter house at Lindisfarne, the Anglo-Saxons of Northumbria. The monastery was a great centre of learning and manuscript production; the Book of Kells is thought by many to have been made, at least in part, on Iona before being taken to Ireland for safety from Viking raids. Iona became a burial place of kings, of Scotland and beyond.

The abbey and the crosses

The Viking age brought repeated raids and the killing of monks, and the community's fortunes rose and fell; a Benedictine abbey was established in the medieval period, fell into ruin after the Reformation, and was restored in the twentieth century. The island preserves early high crosses of carved stone, among the finest of their kind, and the restored abbey church.

A working community

Since 1938 Iona has been the home of the Iona Community, an ecumenical, dispersed Christian community founded by George MacLeod, which combines worship with social and political commitment, so the island functions as a living retreat centre rather than a monument. The crossing requires two ferries and accommodation is limited, which regulates numbers more effectively than any rule; Iona remains a place of pilgrimage and retreat and one of the cradles of Christianity in Britain.

A Manuscript That May Have Started Here

Iona's monks may have started one of the most famous illuminated manuscripts in existence before Viking raids forced the project, or at least its safekeeping, to move to Ireland.

A manuscript that may have started here

Scholars generally believe the Book of Kells, one of the most elaborately illuminated manuscripts to survive from early medieval Europe, was either begun at Iona's monastery or produced by scribes closely connected to it, with the manuscript moved to the monastery at Kells in Ireland at some point, plausibly for safekeeping from the same Viking threat that repeatedly struck the island community directly.

Repeated raids

Iona suffered a series of devastating Viking raids beginning in 795 and continuing over subsequent decades, including an 806 attack in which a significant number of monks were killed, violence severe enough that the community eventually relocated much of its population and its most valuable relics and manuscripts to safer inland locations in Ireland and Scotland.

As this entry's companion article covers

Saint Columba's founding of the monastery and its role as a base for the Christianisation of Scotland and northern Britain are addressed directly in this entry's companion article rather than repeated here.

Cross-Tradition Connections

Associated With

Scotland, Regions

Iona was the island base of Columba's mission in the north.

The custom set aside was that of Iona, whose mission had converted Northumbria. The decision aligned the kingdom with Rome and the Latin West rather than with the Irish tradition that had brought it the faith.
