What makes Moyagher unusual is partly a matter of dispersal: the complex does not hold together as a single, legible unit. A carved graveslab sits inside the nave of the ruined St. Nicholas' church, while a cross associated with the site stands across the road to the south-east, over the townland boundary into Milltown. That division, a medieval cross separated from its parent church by a modern road and an administrative line on a map, gives the place an oddly fractured quality.

The graveyard itself is roughly rectangular, measuring approximately fifty metres on its north-west to south-east axis and around forty metres across. It is defined by earthen banks with outer masonry walls or facings, a construction method that reflects the layered, long-term use common to early ecclesiastical enclosures in Ireland, where boundaries were built up and reinforced over centuries rather than laid out in a single campaign. The church is dedicated to St. Nicholas, and its remains sit within this enclosure. The cross in Milltown townland was recorded as part of the wider site but was not observed during a 2014 examination, leaving its current condition uncertain.
