This medieval earthwork lies just 540 metres east of Piercefield Castle and about a kilometre south of Mullenoran Bridge, with the townland boundary road between Piercefield and Templeoran running 100 metres to the west. The monument consists of a roughly rectangular enclosure measuring approximately 30 metres northwest to southeast and 29 metres northeast to southwest, defended by two substantial earthen banks with a water-filled ditch, or fosse, between them and an additional outer fosse for extra protection.

The interior of the enclosure is dominated by a long rectangular structure, likely a medieval house or barn, which can still be traced through its earthen foundation banks. This building features an internal division suggesting separate rooms or functional areas, with evidence of a doorway at the northeastern end. The ground inside the enclosure slopes gently from southeast to northwest, though quarrying activity has disturbed the southwestern section at some point in the past. Access to the enclosure was via a causeway crossing the defensive ditch on the northern side, a typical feature of these fortified homesteads.

Today, modern field fences border the monument on its northern, eastern and western sides, helping to preserve this glimpse into medieval rural life. The site was surveyed and recorded by the Archaeological Survey of Ireland, with research compiled by Frank Coyne and Caimin O’Brien in August 2017. These moated sites, common across the Irish midlands, were typically built by Anglo-Norman settlers or prosperous farmers between the 13th and 14th centuries, serving as defended farmsteads that combined residential, agricultural and defensive functions in one compact, protected space.
