Hore Abbey was founded in 1266 for the Benedictine Order of monks. The Archbishop of Cashel, nearby, deposed the Benedictines and established the Cistercians from Mellifont Abbey at Hore in 1272. David Mac Cearbhaill, the Archbishop, then entered the monastery as a Cistercian and endowed Hore Abbey with land, mills and other properties that originally belonged to the township.
In 1540, the Abbey was dissolved along with the other monasteries and abbeys. The lands and structures were transferred to the Earl of Ormond (James Butler). Elizabeth I granted the lands to Sir Henry Radcliffe in 1561.
