Most ringforts, the roughly circular enclosures built across Ireland during the early medieval period as farmsteads or high-status residences, have a single earthen bank. This one in County Wicklow has two, making it bivallate, a classification that generally suggests a site of greater importance or one whose occupants felt the need for an extra layer of protection.

The fort sits at a break in a northwest-facing slope, a position that would have offered both outlook and a degree of natural advantage. Its interior is roughly 36 metres in diameter, defined by an earthen bank between three and three and a half metres wide. That inner bank stands noticeably higher on the outside than the inside, reaching nearly one and a half to one and eight metres externally, which is consistent with material having been dug out and piled up to create an imposing outer face. Between the inner and outer banks runs a fosse, a defensive ditch, two to four metres wide and up to a metre deep, which wraps around the southwestern to east-northeastern arc and continues again from the east-southeast to south-southwest. The outer bank itself is lower and narrower, but its presence is what lifts the site into the bivallate category. The original entrance, just over two metres wide, faces north-northwest, and a field boundary now abuts the southeastern edge, the modern agricultural landscape pressing quietly against the early medieval one.
