Mo Lua of Killaloe was a 6th-century Irish monk and abbot who lived during the Early Middle Ages. Originally named Lughaidh, he received his religious training at the monastery in Bangor, County Down. He is primarily recognized as the founder of Killaloe, a settlement that carries his name. As a leader of his monastic community, he established an oratory on Friar's Island, which was eventually succeeded by a stone church near the modern village of Killaloe.
Life and character

While details of his life are limited, Mo Lua is described as a builder and perhaps a hermit. He was known for his hospitality toward both people and animals, following the belief that serving guests was equivalent to serving Christ. Tradition suggests that all living creatures mourned his passing. He was the son of Sochla and Coche (or Carthach), a man from the Corca Oiche sept.
Legacy and veneration
The monastery he established in Clonfert-Mulloe produced the scholar Laidcenn mac Buith Bannaig. His successor and primary disciple was Saint Flannan. Today, he is venerated as a saint within the Catholic and Eastern Orthodox traditions. His feast day is observed on August 4.
