But its proportions tell a different story: roughly 25 metres across at its crest, with a second earthen bank ringing the base of the slope at a diameter of around 45 metres, this is the kind of modest earthwork that rewards a second look.

The site is classified as a fort, a broad term in Irish archaeology that covers a wide range of enclosed settlements and defensive enclosures, most commonly associated with the early medieval period, though some examples are earlier or later. What distinguishes this one, aside from its setting on the northeast end of a northeast-to-southwest drumlin ridge, is the absence of a fosse, the encircling ditch that typically accompanies such earthworks and is often their most visible surviving feature. In its place, a broad entrance ramp, some 12 metres wide, rises up the mound from the southeast, giving the site an almost ceremonial approach. The lower bank, on the eastern to southern arc, has been incorporated into a planted hedge over the years, quietly absorbing the archaeology into the working landscape around it.

The drumlin topography of Monaghan, formed by glacial deposition and characterised by its rolling oval hills, made such ridgeline positions naturally advantageous for whoever built and used this enclosure. The grass cover has kept the overall shape readable, and the combination of the upper and lower banks gives the site a subtle but legible double-ring form when viewed from the slope below.
