The site at Corkagh Beg consists of a sub-rectangular area measuring just over 15 metres from north to south, defined by a low earthen bank that rises barely 20 to 25 centimetres above the surrounding landscape. The eastern section of the bank has almost completely eroded away, leaving only the barest trace of its original form.

This type of earthwork, known as a moated site, was typically constructed during the Anglo-Norman period in Ireland, roughly between the 13th and 14th centuries. These sites served as fortified farmsteads for colonising settlers, featuring a raised platform surrounded by a water-filled ditch or moat for defence. The rectangular shape and modest size of the Corkagh Beg site are characteristic of these rural settlements, which were far more common than stone castles but equally important in understanding medieval settlement patterns in Ireland.

Today, the site sits in waterlogged pasture, its low-lying position contributing to the persistently wet conditions that likely helped preserve what remains of the earthwork. Archaeological survey has found no evidence of a fosse (the defensive ditch that would have surrounded the bank) or any internal features that might indicate buildings or other structures. While the site may appear unremarkable to the casual observer, it represents an important piece of Sligo’s medieval landscape; a reminder of the complex patterns of settlement and colonisation that shaped rural Ireland centuries ago.
