When excavations were carried out ahead of the N9/N10 Kilcullen to Waterford road scheme, archaeologists uncovered a nearly square medieval enclosure measuring roughly 42.8 metres by 42.3 metres, its ditch cut with rounded corners and a northeast-facing entrance just under four metres wide. The pottery recovered from the ditch confirmed a medieval date, and the whole arrangement, with its probable internal bank of slipped earth, suggests a deliberately bounded space, the kind of enclosed settlement or farmstead that organised rural life across Ireland during the medieval period.

What makes this site quietly remarkable is what the medieval enclosure was built on top of. Beneath its ditch lay a prehistoric double penannular ring-ditch, a penannular ring-ditch being a near-circular earthwork cut with a deliberate gap, used in prehistory for burial or ceremonial purposes. Finding two concentric versions of this form beneath a later medieval structure points to a place that held significance across very different periods and very different ways of organising the world. Inside the medieval enclosure, excavators identified a possible structure suggested by two L-shaped features and a line of post-holes, along with pits and hearths. Particularly unusual are the kilns cut directly into the enclosing ditch itself, including keyhole-shaped and figure-of-eight kilns, forms typically associated with grain drying or lime production in an agricultural or domestic context. Just outside the southeast corner, a human burial was found, oriented east to west in the Christian tradition, adding another quiet complication to the already layered biography of this ground.
