Hard to believe this is all that remains of Gallen Priory, County Offaly, a once-great religious house founded in 492AD by Saint Cadoc. After being badly damaged in the 9th century, the monastery here was restored by Welsh monks but several hundred years later, it came under the authority of the Augustinian order, remaining so until the Dissolution of the Monasteries in the 1540s and thereafter falling into decay. Excavations of the site in the 1930s revealed parts of over 200 early Christian burial monuments and these have since been unsympathetically and randomly set in cement walls on the locations of what would have been the east and west gables of the church here, suggesting the inspiration was crazy paving.
