This rectangular earthwork, measuring approximately 60 metres by 50 metres, consists of a raised platform surrounded by a water-filled ditch, or moat, which would have served both defensive and drainage purposes. Dating from the 13th or 14th century, the site likely housed a timber-framed manor house and associated outbuildings, representing the type of fortified farmstead favoured by Anglo-Norman settlers and wealthy Irish families during the medieval period.

Archaeological evidence suggests these moated sites were more than just defensive structures; they were symbols of status and centres of agricultural management. The raised platform would have kept buildings dry in Ireland’s damp climate, whilst the surrounding moat provided protection from wolves and cattle raiders rather than organised military forces. At Castlebanny, the earthworks remain well preserved, with the banks still rising several metres above the surrounding fields and portions of the original moat still visible, though now largely silted up and overgrown with vegetation.

Moated sites like Castlebanny represent a fascinating chapter in Ireland’s medieval history, when the landscape was transformed by new agricultural practices and settlement patterns. Whilst most of the timber structures have long since vanished, these earthworks endure as monuments to a time when the Irish countryside was populated with hundreds of similar fortified homesteads, each one a small centre of power and productivity in an often turbulent age.
