This rectangular earthwork measures approximately 42 metres by 29 metres internally and is defined by substantial earth and stone banks on three sides, whilst the western edge takes advantage of a natural scarp for defence. The banks, which stand 1.5 metres high on the inside and 0.8 metres on the outside, are particularly well preserved on the eastern side where stone facing is still visible, topped with remnants of a stone wall.

The site’s defensive capabilities are enhanced by an external fosse, or ditch, running along the northern and eastern sides; this feature measures 2.5 metres wide and 1.1 metres deep. A single entrance, 2 metres wide, breaches the northern bank, providing the only ground-level access to the interior. Archaeological surveys have identified the remains of a hut within the enclosure, suggesting this was once a living space as well as a defensive structure.

The strategic importance of this location becomes clearer when considering its proximity to a motte and bailey castle just 250 metres west in the neighbouring townland of Carrownagilty. This clustering of fortifications suggests the area held considerable significance during the medieval period, likely serving as a frontier zone or contested territory. The moated site may have functioned as an outlying defensive position or perhaps housed a lesser noble family connected to the main castle, forming part of a broader network of control across this portion of County Sligo.
