This moated site forms a raised rectangular platform, measuring roughly 40 metres from northeast to southwest and 34 metres from northwest to southeast. The platform sits protected within a series of defensive earthworks: an inner bank constructed from earth and stone stands about 4.4 metres wide and 0.7 metres high, though time has taken its toll on the northeastern section, where the bank has worn down almost to ground level.

Between the inner and outer defences lies a fosse, essentially a shallow ditch that would have provided additional protection to whoever occupied this site. This intervening space measures about 4.3 metres wide and reaches depths of nearly a metre. Beyond the fosse, traces of an outer bank remain, though it’s considerably degraded; at 3.4 metres wide and 0.7 metres high, it forms the final layer of the site’s concentric defences. The northeastern side shows significant damage, with both the fosse and outer bank having been completely levelled over the centuries.

A gap approximately 4.2 metres wide in the centre of the northeastern bank likely marks the original entrance to the enclosure. This positioning would have allowed defenders to monitor approaching visitors whilst maintaining the defensive integrity of the other three sides. About 370 metres to the west stands a related motte and bailey fortification, suggesting this area held strategic importance during the medieval period. Together, these earthworks offer a glimpse into how the Anglo-Normans and their successors organised and defended their holdings in medieval Longford, creating fortified sites that served both as residences and symbols of authority in the Irish landscape.
