Hillfort

The National Monuments Service's description

Discovered by Dr James O’Driscoll through the use LiDAR imagery. On the upper slopes of Corballis Hill (OD 853’), between Castledermot and Baltinglass. A very large, bivallate enclosure comprises an upper (above the 800’ contour), roughly circular area (est. diam. c. 190m) of c. 2.13ha, defined by a broad bank (Wth 7.3m). This is in turn enclosed by a much larger, irregularly shaped, outer enclosure defined by a slightly narrower bank (Wth 5.8m). The outer enclosing element broadly follows the contours of the hill (700’ and 600’ contours) and the total area enclosed is some 41.03ha.
The inner enclosure has been almost completely destroyed by modern forestry and no other features within the interior are currently identified. Similarly, the northern perimeter of the outer enclosure is under forestry, and over 60% of its perimeter on its southern side has seen significant disturbance from modern forestry. Likewise, much of the interior has been damaged and it is difficult to identify any possible internal features.
