Sub-rectangular enclosure (early Christian) is a univallate earthwork monument located in County Antrim, Northern Ireland. The enclosure is defined by a single bank and ditch, arranged in a sub-rectangular plan typical of early Christian settlement sites in Ulster. These monuments generally date from the fifth to eighth centuries and commonly served as the focal points of Christian communities, encompassing domestic structures, craft areas and sacred spaces within their defensive boundaries.
The site is situated upon Palaeogene extrusive rocks—specifically mafic lavas and tuffs formed during volcanic activity in the Paleogene epoch. This geology is characteristic of the Antrim basalt plateau, which underlies much of the surrounding landscape and would have influenced both the construction techniques available to the monument's builders and the settlement patterns of early Christian communities in the region.
The enclosure is protected by the Historic Environment Division of the Department for Communities under monument record 4054. Its sub-rectangular morphology and univallate defence distinguish it from the more elaborate ecclesiastical sites of the period, suggesting it may represent a settlement of secondary importance within the early Christian settlement hierarchy of Antrim.
