The enclosure is modest in scale, roughly 25 metres north to south and 29 metres east to west, bounded by a low ruined stone wall, and the church itself sits in the north-western quadrant of this sub-rectangular plot. What gives the place a quiet interest is its position: outside the wall rather than within it, tucked between St. Nicholas' Lane to the north and the Whitening Stream to the south and west, occupying open ground that still feels removed from the town proper.

The earliest gravestones recorded here date to the eighteenth century, though the dedication to St. Nicholas suggests a considerably older ecclesiastical presence on the site. St. Nicholas was among the most widely invoked saints in medieval Ireland and England, and church foundations bearing his name frequently have roots in the Norman or late medieval period. Whether the current remains reflect that earlier foundation or represent a later phase of building is not fully clear from what survives, but the placement outside the town wall is itself suggestive of an older spatial logic, where certain churches, graveyards, and communities occupied the margins of a walled settlement rather than its protected interior.
