This ruined Cistercian monastery located just outside of Cashel, was originally a Benedictine monastery. In 1272, the archbishop of Cashel expelled the monks and Cistercians arrived from Mellifont Abbey.
Hore consisted of a cruciform Gothic church, tower, square cloister and living quarters. Today, the church and sections of the east range remain. There are also fragments of the cloister arcade, which is of interest due to its unique positioning north of the abbey.
