The description is tentative for good reason. What survives is a poorly preserved subrectangular enclosure, roughly 15.8 metres north to south and 14.8 metres east to west, defined by a low earthen bank and an external fosse, that is, a ditch running around the outside. Along the northern side, even that much has been levelled away. The interior is flat, with a slight hollow in the north-east corner, and on the eastern flank there are faint traces of a raised triangular area that may once have formed part of the structure itself. Whether this was a domestic outbuilding, a yard enclosure, or something more substantial is not known.

What makes the site quietly interesting is its relationship to the castle immediately uphill. The two features are clearly part of the same complex, and the positioning of an enclosed structure on lower ground to the south of a defended residence follows a pattern seen elsewhere in medieval Irish landholding, where service buildings, agricultural yards, or ancillary structures clustered around a tower house or fortified site. A fosse-bounded enclosure of this kind, adjoining but subordinate to the main fortification, suggests deliberate organisation of the space rather than casual accumulation. The triangular raised area on the east side adds a further puzzle, its shape not conforming to the more typical rectangular outlines of medieval building foundations, though the archaeology does not resolve what it may have been.
