It measures roughly twenty metres along its longer axis and ten metres across, rising only about a metre above the surrounding ground. That modest profile is part of what makes it interesting: not dramatic enough to be immediately legible, yet clearly shaped by human hands at some point in the past.

What complicates the picture further is the water management visible around it. A channel runs southward from the mound, running parallel to the river and kept separate from it by a low bank, before eventually meeting the river a short distance to the south. That kind of controlled relationship between an earthwork and a nearby watercourse turns up in a range of archaeological contexts across Ireland, from mill leats to drainage features associated with early settlement, and it hints that whatever this mound once was, its purpose was bound up with managing or exploiting the river beside it. The mound itself is oval and entirely grass-covered, which tells us little about its date or function without excavation, but the combination of a shaped earthen mound and a deliberately cut channel is not accidental.

The site sits in farmland in Barrafohona, a quiet townland in east or south Cork. It is the kind of feature that rewards a slow look once you know it is there, particularly the way the low separating bank holds the channel apart from the river for much of its length before allowing them to meet.
