What makes this particular enclosure quietly unusual is the evidence of growth and subdivision written into its very walls: the original perimeter once extended further than it does today, and what is now the southern boundary of this graveyard was, at some earlier point, a shared wall with the adjoining St Brigid's graveyard to the south.

The graveyard is subrectangular in plan, roughly 37 metres on its longer axis and 27 metres across, enclosed by a mortared rubble wall of fairly consistent height, around a metre on the exterior face. St Mary's church sits within its bounds, and access is provided by a gate on the north wall, close to the church's north-west corner, as well as a stile set further along the same wall. A stile, for those unfamiliar with the term, is a set of steps built into or over a wall to allow people to cross on foot without opening a gate, a common feature of Irish ecclesiastical and rural enclosures. The headstones visible today are inscribed and date from the nineteenth and twentieth centuries, the most recent layer of use on a site where the ground itself carries far older associations.
