The site is classified as a flat cemetery, meaning there was no visible mound or monument to signal its presence; the dead were placed in cists, small stone-lined boxes set into the earth, and the land simply closed over them. That anonymity is part of what makes discoveries like this one so striking when they do emerge.

Three urns contained within cists were uncovered during work to level what may be the bailey of a nearby motte and bailey earthwork, the type of fortification introduced to Ireland by the Normans, consisting of a raised mound paired with an enclosed courtyard. A fourth cist, with its urn, was found close to a standing stone lying to the south of the bailey, a detail noted by Kinahan in 1882 and later by Westropp in 1904. The proximity of Bronze Age burial deposits to both a standing stone and a medieval earthwork is not entirely surprising; earlier monuments were frequently reused or built upon in later centuries, their significance perhaps dimly understood or simply absorbed into the landscape. Further cists were identified approximately 300 metres to the west, though their precise locations were not recorded with enough detail to allow them to be pinpointed today, as John Waddell noted in his 1990 study of Irish Bronze Age burials.

What survives above ground at Loggan is difficult to assess with confidence, given how much came to light incidentally rather than through controlled investigation. The flat cemetery, by its nature, leaves little for the eye to read in the landscape.
