That designation alone suggests the site predates the era of modern parish record-keeping, placing it in a category of burial grounds whose origins are often medieval or earlier, and whose stones, where any survive, may carry inscriptions or carvings long worn past easy reading.

The place-name Kilcolgan derives from the Irish Cill Cholgan, meaning the church of Colgan, pointing to an early ecclesiastical foundation associated with a saint of that name. Early Christian communities in the west of Ireland commonly established small churches alongside burial enclosures, and the surrounding landscape around the inner reaches of Galway Bay is thickly layered with such foundations, many of them absorbed into later Catholic parish use and many others simply abandoned to grass and wind. Without further detail on this particular site, it is difficult to say which fate befell this one, but its status as a recorded monument indicates it retains enough physical or historical significance to be considered part of the archaeological landscape of the area.
