What they were recording was a ringfort, the type of roughly circular enclosed settlement that was the standard unit of rural life in early medieval Ireland, typically associated with a single farmstead and its inhabitants. This one sits on the summit of a low east-west ridge near Rathdangan in County Wicklow, with the ground falling away sharply to the south and rising more gently to the north, a position that would have offered both visibility and a degree of natural defence.

The fort itself is largely levelled now, its interior flattened to the point where no entrance, external ditch, or internal features remain visible. What survives is a stretch of earth and stone bank along the southern arc of the enclosure, roughly three metres wide and standing between 1.4 and two metres in height depending on which side you measure from. The bank has been absorbed into the modern field boundary, a common fate for earthworks that were simply too useful as dividing lines to demolish entirely. Notably, the inner face of the bank retains its drystone facing, a construction technique in which stones are carefully laid without mortar, and this stonework continues along the field boundary beyond the original perimeter of the site. The overall diameter of the enclosure is approximately 40 metres, placing it within the typical size range for a single-family rath of the early medieval period.
