The ringfort, roughly 45 metres along its north-south axis and 25 metres east to west, survives in fair condition, though the southern arc of its enclosing bank has vanished entirely, leaving only the northern and eastern stretches still legible. A later field wall has been laid directly on top of the original bank between the north and south-east, the kind of quiet overwriting that happened on farmland across Ireland when boundary materials were simply where you found them.

Ringforts, sometimes called raths, were the most common form of enclosed settlement in early medieval Ireland, typically dating from roughly the fifth to the twelfth century. They functioned as enclosed farmsteads, the bank and accompanying ditch marking out a household's space rather than serving any serious military purpose. What makes the Ardfintan example particularly worth noting is what the interior appears to contain. A probable souterrain runs beneath the ground inside the enclosure; souterrains are stone-lined underground passages or chambers, built during the early medieval period and thought to have served as cool storage spaces or refuges in times of danger. Associated with the site is also a cashel, ringfort, or barrow group, suggesting this was not an isolated feature in the landscape but part of a wider pattern of settlement and activity in the area. The reference to O'Flanagan's fieldwork places the site within a documented local record, though the details of when it was last actively used or modified remain unclear.
