The site is defined by substantial earthen banks on three sides; the northern bank is particularly impressive at 8.7 metres wide with an internal height of 0.4 metres and an external height reaching 2 metres. The eastern and western banks are somewhat smaller, ranging from 3 to 4.5 metres in width and standing between 0.7 and 1.1 metres high. The southern side lacks any surviving bank, with only the modern field boundary marking this edge of the enclosure.

At the heart of this earthwork sits a church, creating what appears to be an ecclesiastical enclosure typical of early medieval Irish religious sites. The 1838 Ordnance Survey six-inch map depicts this rectangular enclosure surrounding the church and labels it as ‘Site of Chapel and Raheen’, suggesting the site’s long-standing recognition in local memory and cartographic records. The name ‘Raheen’ itself derives from the Irish ‘ráithín’, meaning a small fort or earthwork, which perfectly describes this monument.

Archaeological survey has revealed no evidence of a defensive fosse or ditch around the perimeter, nor any obvious entrance features through the surviving banks. This absence of defensive elements, combined with the central church, suggests the earthwork may have served primarily as a boundary defining sacred space rather than as a fortification. The site represents one of many such ecclesiastical enclosures scattered across the Irish landscape, physical remnants of the country’s rich early Christian heritage.
