Iona Abbey: The Cradle of Celtic Christianity
The ferry crossing from Fionnphort on the Isle of Mull takes only a few minutes, yet it carries you across one of the great thresholds of European religious history. Iona is a small island of the Inner Hebrides, barely three miles long, exposed to Atlantic weather and fringed by white shell-sand beaches. In the year 563 an Irish monk named Columba, known in Gaelic as Colum Cille, landed here with a small band of companions and founded a monastery. From that modest settlement of huts and a timber church, Christianity spread across much of Scotland and into northern England, manuscripts of astonishing beauty were produced, and kings were carried across the water for burial. Few places of comparable size have shaped a continent's faith so profoundly.
Columba's exile and arrival in 563
Columba was born into the powerful Uí Néill kindred of northern Ireland and was already an experienced founder of monasteries before he ever saw Iona. Tradition holds that he left Ireland in the aftermath of a bloody conflict, though the precise reasons for his departure remain debated by historians; whether penance, politics, or missionary ambition drove him, the result was the same. He crossed the sea to the western coast of what is now Scotland, then part of the Gaelic kingdom of Dál Riata, whose rulers had close ties to his own kin. The island he settled offered what Celtic monasticism prized most: seclusion at the edge of the inhabited world, combined, paradoxically, with excellent connections. The sea lanes of the Hebrides were the motorways of the early medieval world, and Iona sat astride them. From this base Columba could reach Ireland, the Scottish mainland, and the islands with equal ease. He led the community for more than three decades until his death in 597, by which time Iona was already famous.
What the first monastery looked like
Visitors expecting the grey stone abbey to date from Columba's time are often surprised: nothing of the first monastery survives above ground in its original form. The early buildings were of timber, wattle and turf, and they have long vanished. What does survive is the vallum, the great earthwork bank and ditch that enclosed the monastic precinct, parts of which can still be traced in the fields around the abbey. Within it stood a church, communal buildings, workshops, and the cells of the monks. On the small rocky rise called Tòrr an Aba, just west of the later abbey church, excavation has supported the tradition that Columba had a writing hut where he worked and from which he could watch over the community. The monks farmed, fished, copied manuscripts, and followed a demanding round of prayer. Our best window into this world is the Life of Columba written around a century after the saint's death by Adomnán, the ninth abbot of Iona and a major scholar in his own right. His account, rich in miracles but also in everyday detail, remains one of the most important documents of early medieval Britain and Ireland.
A missionary powerhouse
Iona was never merely a retreat. It became the mother house of a far-flung family of monasteries, a network that historians call the familia of Columba. Monks trained on Iona founded and staffed religious houses across the Hebrides, in Ireland, and on the Scottish mainland, and the abbey's influence reached deep into the lands of the Picts. Its most celebrated missionary venture came in 635, when the monk Aidan was sent from Iona at the invitation of King Oswald of Northumbria to establish a monastery on Lindisfarne, off the northeast coast of England. From Lindisfarne, Christianity in the Irish tradition spread through much of Anglo-Saxon England. The distinctive customs of the Columban church, including its method of calculating the date of Easter, eventually gave way to Roman practice, but the debt northern Britain owed to the small Hebridean island was immense and openly acknowledged by early writers such as Bede.
Stone crosses and the scriptorium
The eighth century was Iona's artistic golden age. The monastery's carvers produced some of the earliest and finest of the great Celtic high crosses, working out in stone the ringed form that would become an emblem of Gaelic Christianity. St Martin's Cross still stands where it was raised more than twelve hundred years ago, its faces carved with biblical scenes and serpent-and-boss ornament. The remains of St John's Cross and St Oran's Cross, now conserved in the abbey museum, show the same workshop pushing the limits of what stone could do; a replica of St John's Cross stands outside the west door of the abbey church. The scriptorium was equally ambitious. Many scholars believe that the Book of Kells, the most lavishly decorated Gospel book to survive from the early medieval world, was begun on Iona around the year 800, before being taken to Ireland. Whether wholly or partly made on the island, it belongs unmistakably to the artistic culture that Iona nurtured.
Vikings, martyrs, and the road to Kells
Iona's wealth and its exposed position made it an early target when Norse raiders appeared in the Hebrides. The monastery was attacked for the first time in 795, and further raids followed in the following decades. In 806 raiders killed a large number of monks at the bay on the island's eastern shore still known as Martyrs' Bay. In response, the community built a new monastery at Kells in Ireland, and much of Iona's treasure, its relics, and probably its great Gospel book were transferred there for safety. Yet Iona was never abandoned. A community persisted on the island through the Viking Age, and as the Norse settlers of the Isles themselves converted to Christianity, the island's sanctity was honoured by the very culture that had once plundered it.
Kings in the graveyard: Reilig Odhráin
Beside the abbey lies Reilig Odhráin, the burial ground named after Oran, a companion of Columba, with the small twelfth-century St Oran's Chapel at its heart. Medieval tradition claimed this ground as the resting place of a long line of early Scottish kings, among them, famously, both Macbeth and his rival Duncan, as well as kings from Ireland and Norway. Modern historians treat the traditional lists with caution, but there is no doubt that Iona was a burial place of the highest prestige for centuries. Coffins were carried along the cobbled Street of the Dead, a stretch of which survives, from the shore to the graves. The tradition never entirely died: in 1994 John Smith, the leader of the British Labour Party, was buried on Iona. The graveyard also holds a remarkable collection of carved medieval grave slabs commemorating the warrior aristocracy of the western seaboard.
From Benedictine abbey to modern restoration
Around the year 1200 Ranald, son of Somerled, the great ruler of the Isles, refounded Iona as a Benedictine abbey, and an Augustinian nunnery was established nearby at about the same time; its serene pink-granite ruins remain among the best preserved medieval nunneries in Scotland. The abbey church that visitors enter today is essentially this medieval building, altered over the centuries. Monastic life ended with the Scottish Reformation in the sixteenth century, and the buildings slowly decayed into picturesque ruin, sketched and lamented by travellers. In 1899 the eighth Duke of Argyll transferred the site to the Iona Cathedral Trust, and the abbey church was restored for worship in the early twentieth century. From 1938 the Iona Community, founded by George MacLeod, rebuilt the surrounding monastic buildings, and the community still keeps a living rhythm of worship and hospitality there. The historic site is today cared for by Historic Environment Scotland, and the island welcomes many thousands of pilgrims and visitors every year.

Iona rewards slow travel: the ferry from Mull, the walk up the Street of the Dead, the quiet of St Oran's Chapel before the crowds arrive.
