What makes the Mooretown example quietly compelling is a single architectural detail: its entrance, just half a metre wide, was deliberately oriented towards a specific destination. Whoever dug that narrow gap in the enclosure ditch was pointing it, almost precisely, at the Oldtown ecclesiastical complex to the north-north-east.

The site was first detected through a geophysical survey carried out under Licence 06R067 ahead of a proposed development, and subsequently confirmed by test excavation under Licence 08E0303. What the excavators found was a circular enclosure ditch roughly 30 metres in diameter, with the ditch itself measuring about 2.3 metres across. A ringfort, for those unfamiliar with the term, is a type of early medieval enclosed farmstead, typically circular and defined by one or more earthen banks or ditches, which served as a combination of domestic space and livestock enclosure. Inside the Mooretown example, archaeologists recorded pits, postholes, and an L-shaped ditch. The postholes along the interior edge of the main ditch suggest the original structure included a palisade, a timber fence or screen set just inside the ditch line, adding a physical barrier beyond the earthwork itself. That the entrance aligns with the Oldtown religious site is not explained in the excavation record, but the precision of the orientation, noted by Frazer in 2008, suggests intention rather than coincidence.

Because the site was identified in advance of development and confirmed through controlled excavation, its current condition and visibility depend largely on what was agreed at the planning stage. It sits within the barony of Nethercross in north County Dublin, an area with a notable concentration of early medieval activity. Anyone with an interest in the archaeology of the region would find the Oldtown ecclesiastical complex worth investigating as a companion site, given that Mooretown's entrance was expressly aimed in that direction.
