Originally depicted on the first edition Ordnance Survey map from 1840-41, the monument once formed an oval enclosure measuring approximately 50 metres north to south and 38 metres east to west, defined by multiple banks and defensive ditches. When archaeologist Flynn documented the site in 1913, he described it as a large, slightly oval mound with fosses and ramparts constructed where it cut across the hilltop, whilst the sides had been scarped away to enhance its defensive capabilities.

The ringwork’s destruction tells a familiar story of industrial progress versus archaeological preservation. Aerial photographs from 1966 show the monument still clearly visible amongst the undulating pasture land, but by 1974 the expanding gravel quarry had inflicted severe damage to the structure. Today, visitors to the area would find no trace of this once imposing defensive earthwork; the entire monument has been quarried away, leaving only the historical documentation to tell its story.

The location of this lost ringwork places it within a significant medieval landscape. Several other historical features once dotted the immediate vicinity, including another enclosure about 100 metres to the east, a motte and bailey castle 110 metres to the southeast, and a church with its associated graveyard approximately 215 and 180 metres to the east respectively. This cluster of medieval structures suggests Corrogemore was once a settlement of some importance, where defensive earthworks, religious buildings, and community spaces formed an interconnected medieval complex that has now largely vanished beneath modern development.
