This trapezoidal enclosure, measuring roughly 50 metres from northeast to southwest and tapering from 64 metres to 53 metres across its width, stood here for centuries before being levelled in 1959. The site first appeared on the 1839 Ordnance Survey map and remained a notable landscape feature through to the 1900 revision, when such defensive structures were still considered worth documenting by military cartographers.

According to the landowner’s recollections from the time of its destruction, the monument consisted of a flat platform surrounded by an earthen bank standing about a metre high and two metres wide, with an external waterlogged ditch measuring 2.5 metres across and approximately a metre deep. During the levelling work, workers discovered a stone hone; a whetstone used for sharpening tools and weapons, offering a tangible connection to the daily lives of its former inhabitants. The enclosure’s unusual trapezoidal shape sets it apart from the more common circular ringforts found throughout Ireland, suggesting it may have served a specialised defensive or administrative purpose.

The real intrigue lies in its relationship with the large circular enclosure situated just 20 metres to the southwest. While historian Barry classified the trapezoidal structure as a moated site in 1977, its proximity to the circular earthwork raises fascinating questions about their connection. They may represent different phases of occupation, with one replacing the other as needs and defensive strategies evolved. Alternatively, the trapezoidal enclosure might have functioned as a bailey; an outer defensive courtyard attached to the main circular stronghold, creating what would essentially be a ringwork and bailey complex similar to those found in Norman territories. Recent satellite imagery has revealed that the circular enclosure appears to have an additional outer bank and fosse that directly abuts the trapezoidal structure, suggesting these monuments were deliberately linked, though whether they were built simultaneously or adapted over time remains an archaeological mystery.
