The site, measuring roughly 33 metres from northeast to southwest and 29 metres from northwest to southeast, consists of a grass-covered platform surrounded by the remains of defensive moats and banks. A seasonal stream bed curves around the western and northern edges of the site, though it now runs dry for much of the year.

The earthwork’s defensive features are still clearly visible despite centuries of weathering. Three sides of the rectangle are defined by flat-bottomed moats of varying dimensions; the northeastern moat spans 5.5 metres at its base and reaches half a metre deep, whilst the southeastern moat is narrower at 3.3 metres wide but slightly deeper at 0.7 metres. The northwestern boundary shows only shallow traces of a moat, now just 0.1 metres deep, and the southwestern edge is marked by a modest scarp rising 0.2 metres above the surrounding ground. What makes this site particularly interesting is the evidence of additional outer defences, including an overgrown bank on the northeast side that rises 1.4 metres on its inner face, and traces of another bank and moat system to the southwest.

These moated sites, common throughout medieval Ireland, typically date from the 13th to 14th centuries and were often associated with Anglo-Norman settlement or wealthy Gaelic families adopting new defensive architectural styles. The double bank and moat arrangement at Parkeel suggests this was a site of some importance, possibly serving as a fortified farmstead or minor manor house. Today, the earthworks stand as a subtle but fascinating reminder of how medieval communities shaped the Irish landscape, creating defensive homesteads that balanced practical fortification with agricultural needs.
