The old course of the Dooyertha River once flowed immediately east of this fortified enclosure, creating a natural barrier between it and a neighbouring rath. Today, the river has shifted southward, leaving both monuments high and dry on the same side of its banks.

The moated site takes on a roughly wedge-shaped footprint, stretching 36 metres from northeast to southwest and nearly 18 metres from northwest to southeast. Two earthen banks with an intervening fosse, or defensive ditch, define what remains of the structure, though time has erased any visible traces of these enclosing elements along the northern, eastern, and southeastern sections. A well-preserved causewayed entrance gap at the northwest corner shows where medieval inhabitants once crossed into the protected space.

This fortification wasn't alone in the landscape; approximately 500 metres to the west-northwest stands a motte and bailey, suggesting this area held strategic importance during the medieval period. The proximity of these defensive structures, combined with the natural protection once offered by the river, paints a picture of a carefully planned defensive network. Archaeological surveys conducted by University College Galway have documented these features, preserving knowledge of how medieval communities organised their settlements and defences in the Irish countryside.
