This rectangular enclosure, measuring approximately 40 metres from east to west and 33 metres from north to south, is now marked only by low earthen scarps that trace its original boundaries. The site sits just north of a tower house, suggesting it once formed part of a larger defensive complex typical of late medieval and early modern Ireland.

Bawns were fortified enclosures that served as protective courtyards around tower houses and castles throughout Ireland from the 15th to 17th centuries. They provided a secure area where cattle could be herded during raids, and where everyday activities could be carried out under the watchful eye of the tower house garrison. The earthwork remains at Shean More, whilst modest in appearance today, would have originally featured more substantial walls or palisades, creating a formidable defensive perimeter around the tower house.

The positioning of this bawn on the slope rather than the ridge summit is noteworthy, as it suggests the builders prioritised proximity to the tower house over commanding the highest ground. Today, visitors to the site need a keen eye to trace the low scarps that mark where walls once stood, but these faint impressions in the landscape represent centuries of Irish history; from clan warfare and cattle raids to the gradual abandonment of these fortified homesteads as more peaceful times emerged.
