The town most probably owes its origin to the foundation of
Clane Friary in the sixth century, from about 520 A.D., when
Ailbe of Emly, Bishop of Ferns, founded an Abbey in Clane and made St. Senchel the Elder its first Abbot.
Saint Ultan Tua, who used to put a stone into his mouth to prevent him from speaking during Lent, and his brother Fotharnaise, are said to have been buried in Clane. They were brothers of Maighend, Abbot of Kilmainham, from whom the parish and church of Mainham, near Clane, were probably called.
King Mesgegra's Mound claims links to the legendary first-century AD king
Mesgegra of Leinster. It was later used by
Normans. The ruins of the Franciscan monastery founded at Clane by Sir Gerald FitzMaurice, 3rd Lord Ophaly, in 1272 still exist. In 1542, Henry VIII's Commissioner granted the site and precincts of this House of Friars, manor or preaching-house of the preaching Friars of Clane to Robert Eustace, Roger Roche and Ed. Brown for £177. Besides about of land in the neighbourhood, its possessions consisted of a church, cemetery, chapter-house, dormitory, store, kitchen, two chambers, stable and orchard. The dormitory and other buildings probably stood on the north side of the Abbey Church, and have long since completely disappeared. The parish of Clane has the distinction of being the place where the
rebellion of 1798 broke out; a battle between the
United Irishmen and the
Yeomen forces led by Richard Griffith took place on Coiseanna Hill by the modern Woods Centre. The rebels were easily defeated, and the survivors fled to
Timahoe with the rest of the North Kildare rebels. ==Features and amenities==
