This important monastic site, founded in the 7th century by St Moling, was the legendary burial place of the Kings of Leinster. The remains include four church buildings dating from the 10th to the 15th centuries, the stump of a round tower and a 9th-century high cross. Nearby is the grave of General Thomas Cloney, a hero of the 1798 uprising, and a monument raised by 'St Mullins exiles in New York' marking the tomb of Art, King of Leinster (1357–1416).
