Old Mill

Detached three-bay two-storey former watermill, built c.1780, on bank of River Suir. Pitched roof, covering gone. Rubble limestone walls with dressed window surrounds, lintels and sills. Evidence in south wall of earlier phases of building. Carved grotesque head on the exterior of the north wall above the doorway. Timber and steel undershot mill-wheel to east gable on millrace running parallel to the river. Some machinery and mill stones in interior.

The ruined former watermill forms a picturesque component of the historic precinct of Holycross Abbey, due to its setting on the bank of the River Suir adjoining Holycross Bridge. It has the ability to demonstrate its former industrial use as a watermill due to the survival of components such as the millrace and the timber undershot waterwheel. It is a rare surviving early industrial element from the eighteenth century. The evidence for earlier periods of construction suggests that the building may have been a monastic mill.
