That interior feature is not common, and its purpose remains the kind of question that Irish field archaeology tends to leave unanswered without excavation.

The site is a rath, the most widespread monument type in the Irish countryside, usually understood as a farmstead enclosure of the early medieval period, roughly 500 to 1000 AD. A rath consists of one or more earthen banks with a ditch, known as a fosse, separating them, enclosing a roughly circular or oval area where a household and its outbuildings would have stood. This example measures approximately 53.6 metres north to south and 40.9 metres east to west, making it a reasonably substantial example. It has two banks with an intervening fosse between them, a configuration sometimes described as bivallate, which may indicate higher status or simply a desire for greater security. Entry was made at the south-east, where a causeway crosses the fosse, the original raised approach still legible in the earthwork. The site is described as being in fair condition. Roughly 150 metres to the north-north-west, a separate enclosure has been recorded, suggesting this was not an isolated farmstead but part of a wider pattern of early settlement across this stretch of ground.
