Historical Ordnance Survey maps from 1842 show this structure as a hachured rectangular enclosure, though by the time the 1904 and 1938 maps were drawn, it had already begun to merge with the surrounding field fence system, with only half its original form still clearly marked. Today, the site has been completely levelled, leaving no surface traces visible to the casual observer.

When archaeologist Hartnett documented the site in 1939, he recorded the fort’s dimensions as 164 feet running north to south and 98 feet east to west. The enclosure featured stone-faced banks along its eastern and southern sides, whilst the northern and western boundaries were defined by a scarp measuring approximately 4 feet in height. This type of rectangular fortified enclosure represents a common defensive structure in medieval Ireland, likely serving as a protected farmstead or minor stronghold.

The site forms part of the broader archaeological landscape of Mid Cork, which includes numerous similar earthworks and fortifications from various periods of Irish history. Though the physical structure has vanished beneath centuries of agricultural activity, its presence in historical records and maps provides valuable insights into the settlement patterns and defensive strategies employed by communities in medieval Cork. The nearby mill site adds another layer of historical significance, suggesting this was once a hub of local agricultural and economic activity.
