The Dominican Priory of St. Patrick was founded at Tulsk in 1448 in the grounds of the present-day Tulsk Cemetery.
Tulsk was the seat of the O’Conor chieftains, patrons of the priory, where a small community of about six monks lived, providing preaching and a place of worship, charity to the poor, and medical help to the local population. In the following centuries graves were made and headstones erected, scattered through the ruins.
