Volunteers on Lismore, a tiny island of about 190 people off Oban in western Scotland, have uncovered burial grounds, carved stonework, early buildings and large numbers of gold- and silver-casting crucibles at the site of a sixth-century monastery founded by Saint Moluag. Led by archaeologist Dr Clare Ellis and funded by a local historical society, the dig suggests Lios Mór was a high-ranking site of international importance comparable to Iona (the famed island monastery founded by Saint Columba), not an overlooked backwater. Experts say the findings reshape understanding of how Christianity spread through northern Britain, and the results will be published in the journal Antiquity.
