The monument no longer exists in any recoverable form, absorbed first by a concentrated settlement in the late nineteenth century and then by the agricultural development that followed. What survives is a description, recorded by Kinahan between 1879 and 1888, of something genuinely unusual: two concentric stone circles, one inside the other, with diameters of roughly three and four metres, enclosing four pits packed with ashes and burnt stone. More ash and burnt material lay between the rings to the north-east and south-west, and the whole arrangement was sealed beneath a clay mantle extending to perhaps six or eight metres across. It is the kind of careful, layered construction that suggests deliberate ritual purpose rather than casual disposal.

The site sat towards the top of a south-facing slope, just below a col between two low hills lying roughly four hundred metres to either side. That elevated, between-places position may itself be significant; such spots were often chosen for monuments marking boundaries, whether territorial or between the living and the dead. The ring-cairn, a type of monument in which a circular bank or ring of stones encloses a central space without fully covering it, was noted by Ryan in 1981 as a possible Linkardstown-type cist. Linkardstown cists are a specifically Irish Neolithic burial tradition, characterised by large stone-lined graves beneath round mounds, often containing crouched inhumations with pottery. The suggestion places the Cummer monument in an interpretive grey area, somewhere between burial types and periods. Around it lay a broader complex: a separate cist burial, a flat cemetery discovered on a different occasion, and a fulacht fia nearby. A fulacht fia is a type of ancient cooking or processing site, typically identified by a horseshoe-shaped mound of burnt and fire-cracked stone beside a trough. Together, these features point to a landscape that was used, marked, and returned to across a considerable span of prehistoric time, even if no trace of it remains above ground today.
