Three mounds of varying size, interspersed with scattered stone rubble, are thought to represent the remains of a mill that once operated here, pressed between the river to the north and the ruins of Ballybeg priory to the south. The largest of the three measures roughly 9.5 metres by 9 metres and rises to about 1.75 metres, with a noticeably flat top. A second, more irregular mound lies approximately 8 metres to the east and is considerably longer, stretching around 25 metres east to west. A third, smaller mound sits to the west of the central one, with a low earthen bank extending several metres to the south-east from its base. Elsewhere in the same field, a rectangular enclosure and further earthworks may also be connected to the mill complex.

The earliest documentary evidence for milling activity here comes from the Down Survey, the ambitious mid-seventeenth-century mapping project commissioned by the Cromwellian administration to catalogue Irish land before its redistribution. The barony map produced between 1655 and 1656 marks a mill in this area, and a second mill is also indicated on the northern bank of the Awbeg at roughly the same time. The Awbeg, a tributary of the Blackwater, would have provided reliable power for milling, and the proximity to Ballybeg priory, an Augustinian foundation, suggests the mill may have served the monastic community at some point in its working life, though the precise relationship between the two sites remains unclear. The boggy ground that now surrounds the mounds would have been a practical asset for a water-dependent industry, however inconvenient it makes the site today.
