This rectangular grass-covered platform measures 32 metres from north-northwest to south-southeast and nearly 28 metres from east-northeast to west-southwest. What makes this site particularly striking is its defensive water-filled moat system; flat-bottomed channels ranging from 6.5 to 7 metres wide at the top surround the platform on three sides, whilst the river itself forms the natural boundary to the west. The moats maintain depths between 0.9 and 1.3 metres internally, slightly deeper on the external sides.

The site’s defences are further enhanced by outer banks on the eastern and southern sides, though these are relatively modest in scale, standing just 0.3 to 0.6 metres high. A four-metre-wide causeway at the centre of the northern side would have provided the primary access point to this fortified enclosure, which altogether spans nearly 50 metres at its greatest extent. The reed-filled moats today give us a glimpse of how this defensive system would have functioned, keeping the enclosed area secure whilst allowing controlled entry and exit.

Across the stream to the southwest, in the neighbouring townland of Ballybeg, lies what appears to be an associated enclosure or annexe. This secondary site presents as a raised rectangular platform measuring 43 by 33 metres, defined by a half-metre-high scarp on its southwestern edge and bounded by field drains and the stream on its other sides. The relationship between these two sites suggests a more complex medieval settlement pattern along this stretch of the Ogulla River, possibly representing different phases of occupation or complementary functions within a single estate.
