When first recorded on the Ordnance Survey maps of 1840-41, the monument appeared as two conjoined oval enclosures; an impressive defensive structure that commanded sweeping views across the surrounding countryside. The main motte measured approximately 25.6 metres in diameter and stood between 6.7 and 9.1 metres high, with a defensive trench running around its base that was 2.4 metres wide. A fosse, or defensive ditch, encircled parts of the structure, though even by the 1840s much of it had already been destroyed on the southeast and south sides.

The castle complex consisted of more than just the central motte. According to early 20th century descriptions by local historian Flynn, the main oval mound connected via a gangway to a large garth, or enclosed courtyard, which had its own defensive fosses and ramparts at both ends. The sides of both structures were naturally protected by the steep slopes of the hill itself, eliminating the need for artificial defences there. A secondary garth extended down the eastern hillside, creating a substantial fortified complex that would have dominated the local landscape. The entire circumference at the base of the motte measured an impressive 141.7 metres, with the remaining portions of the fosse reaching heights of up to 4.2 metres in some places.

Unfortunately, this significant medieval monument has suffered extensive damage over the centuries. While aerial photographs from 1966 still showed the castle’s outline clearly visible, quarrying activities had caused severe damage by 1974, and today no visible trace remains above ground. The site sits within an area of active gravel extraction, surrounded by undulating pasture land. Several other archaeological features dot the immediate landscape, including additional enclosures to the north and northwest, and the remains of a medieval church and graveyard approximately 100 to 140 metres to the northeast, suggesting this was once an important centre of medieval life in south Tipperary.
