Easy to step over, easy to miss entirely, it is one of two features within the fort that archaeologists have tentatively identified as possible hut sites, meaning the remains of ancient domestic structures where people once actually lived, or at least sheltered, within the protection of the hillfort's walls.

The feature sits on level ground about fifty metres west of the hill's summit, positioned fifteen metres inside the innermost rampart of Rathcoran. Hillforts of this type, large enclosures defined by earthen or stone ramparts running around the upper slopes of a hill, are found across Ireland and Britain and are generally associated with the Iron Age, though some were built earlier and many saw long, complicated histories of use and reuse. The interior of Rathcoran is not densely packed with obvious structures, which makes the presence of even a modest raised platform with a stony bank worth pausing over. The second possible hut site nearby suggests this was not simply a one-off feature but part of some pattern of occupation within the enclosure, however sparse or intermittent that occupation may have been.
