The earthworks at Clogharevaun, Co. Galway, had survived for centuries as a set of grass-covered banks on a gentle rise overlooking a bend in the Clogharevaun River, only to be removed by land reclamation in September 1995, months after the state had moved to protect them.

The system comprised three rectangular fields and traces of two others, their boundaries defined by low earthen banks between one and two and a half metres wide and reaching no more than 0.7 metres in height. The largest field covered 14 hectares and ran alongside the southern wall of a bawn, the walled enclosure attached to a nearby tower house. In the Irish context, a bawn typically served as a defended yard or cattle enclosure adjoining a tower house, and the relationship between the two here is suggestive. A further two partial fields were recorded approximately 20 metres to the north-east. Writing in 1989, Cody proposed that the field system was most likely associated with the occupancy of the tower house itself, meaning the fields and the fortified residence probably functioned together as part of the same landholding and agricultural economy. By 1995, when Connolly noted their loss, all of that physical evidence had been erased from the ground.

What remains today is the tower house and its bawn, still standing on the same rise above the river. The field system exists now only in the 1989 survey record, a diagram, and a preservation order that came too late to preserve anything.
