There is compelling evidence suggesting the existence of an early monastic site on Inis Píc. This is noted in the Annals of the Four Masters, compiled between 1632 and 1636, where one of the annals mentions the abbot ‘Sealbhach of Inis Píc’ in 821. Further evidence comes from Monasticon Hibernicum, published in 1786, which names St. Mochuda as the founder of a monastery. According to this account, he placed three brothers with the bishop, alongside twelve of his disciples, within the monastery.
Additionally, a 12th-century charter of Henry II describes the island as an Anglo-Norman property and references a church or religious house located there.
However, despite these historical references, no physical traces of the elusive monastic site have yet been discovered.
