The site offers extensive views across the surrounding countryside, a strategic advantage that would have been crucial to its original builders. The motte itself is a small, oval mound with steep sides, standing between 4 and 6 metres high. At its base, it measures approximately 26 metres from east-northeast to west-southwest and 21 metres from north-northwest to south-southeast. The summit is relatively flat, spanning about 20 metres by 13 metres, where a wooden tower or keep would have once stood.

A shallow fosse, or defensive ditch, measuring 4.7 metres wide and half a metre deep, separates the motte from its associated bailey to the northeast. The bailey appears as a low, roughly square platform about 11 metres on each side, defined by a scarp that varies in height from 20 to 75 centimetres. This would have been the enclosed courtyard where domestic buildings, stables, workshops and other structures essential to castle life were located.

The entire complex is encircled by what remains of a wide, shallow fosse that once provided an additional line of defence. Though now largely filled in, this outer ditch still measures 10.1 metres in width with a maximum depth of 1 metre. These earthwork castles were typical of Anglo-Norman fortifications in Ireland during the 12th and 13th centuries, representing the first wave of castle building that followed the Norman invasion of 1169. The Glebe example, recorded by Patrick F. O’Donovan in March 2012, stands as a well-preserved reminder of this turbulent period in Irish history.
