On 10th March 520, Saint Kessog, (born c. 460 Cashel, Tipperary, Ireland) an Irish missionary and the original patron saint of Scotland, is killed at Bandry, on the western shore of Loch Lomond.
His headquarters for spreading Christianity in the Lennox and Loch Lomond area is thought to have been Monk’s Island (Inchtavannach) on Loch Lomond. His name was used as a war-cry for the Scots of Dál Riata; Saint Kessog is often depicted in battledress armed with a bow.
The Church of Scotland’s Luss Parish Church is dedicated to Saint Kessog and stands on the site of a church founded by him in 510. In 2010 the church celebrated 1500 years of worship.
