The rectangular enclosure measures 33.1 metres from northeast to southwest and 21.2 metres from northwest to southeast, surrounded by a fosse (defensive ditch) that reaches depths of 4.35 metres. The fosse is particularly deep along the western, northwestern and northeastern sides, becoming shallower on the lower portions of the slope. A dyke, measuring up to 2.2 metres deep and 6.2 metres wide, extends approximately 30 metres southwest from the southern end of the enclosure’s southwestern side; local tradition holds that it once continued another 50 metres to reach a well in the neighbouring field.

The site’s most intriguing feature is a natural spring well located in the fosse on the northwestern side, which remained in use as a domestic water source until the 1950s according to local residents. A stepped entrance leads down from the exterior to a low causeway that crosses the fosse just southwest of the well, providing access to the interior. The enclosed area shows clear signs of deliberate landscaping, with the surface raised on the southeastern and southern sides to compensate for the natural hillslope, creating a more level living space.

The interior terrain remains undulating, with a notable depression measuring 6 metres long, 3 metres wide and 0.9 metres deep on the southwestern side, surrounded by a slight rim. This carefully engineered medieval site demonstrates how our ancestors adapted natural landscapes for defensive purposes whilst maintaining practical considerations like water access, revealing the sophisticated planning that went into these rural fortifications scattered across the Irish countryside.
