Saint Columba (7 December 521 – 9 June 597), sometimes referred to as Columba of Iona, or, in Old Irish, as Colum Cille (meaning "Dove of the church") was an outstanding figure among the Gaelic missionary monks who, some of his advocates claim, introduced Christianity to the Kingdom of the Picts during the Early Medieval Period. He was one of the Twelve Apostles of Ireland. Columba was born to Fedlimid and Eithne of the Cenel Conaill in Gartan, near Lough Gartan, County Donegal, in Ireland. On his father's side he was great-great-grandson of Niall of the Nine Hostages, an Irish high king of the 5th century.
In 563 he travelled to Scotland with twelve companions, where according to his legend he first landed at the southern tip of the Kintyre peninsula, near Southend. However, being still in sight of his native land he moved further north up the west coast of Scotland. In 563 he was granted land on the island of Iona off the west coast of Scotland which became the centre of his evangelising mission to the Picts.
