What appears modest from the north, rising just 2.2 metres above the surrounding ground, reveals itself to be considerably more imposing on the southern and eastern sides, where it climbs to 5.8 metres. The difference is not accidental. Whoever shaped this mound worked with the natural lie of the land, exploiting an existing slope to amplify its presence on the higher, more visible aspects.

The mound is circular, roughly 30 metres in diameter at its base, and belongs to a broader category of earthworks found across Ireland whose precise function remains open to interpretation. Such mounds could serve as burial monuments, ceremonial sites, or markers of territory and status, and without excavation it is rarely possible to say which with certainty. What makes the situation at Ardogelly particularly interesting is its relationship to a second monument close by. A rath, the remains of a roughly circular enclosure typically associated with early medieval settlement and farming, sits approximately 30 metres to the north. Whether the two were ever used in concert, or whether the rath was simply built near an already ancient landmark, is unknown, but the pairing is a pattern repeated at other sites across the country. Quarrying has since removed a portion of the mound's south-eastern edge, leaving the site slightly lopsided, a reminder of how routinely such monuments were treated as convenient sources of stone or fill in more recent centuries.
