The earthwork is a rath, the most common type of ringfort in Ireland, typically a raised enclosed area defined by one or more earthen banks and ditches, used as a farmstead during the early medieval period. What makes this one quietly interesting is how much engineering thought went into it: the interior has been deliberately raised on its eastern side to level out the natural slope of the hillside, a practical adjustment that is easy to overlook but speaks to careful construction. The outer ditch, running from south-south-east around to north-north-east, still survives to a depth of around 1.75 metres on that arc, and the entrance gap, roughly six metres wide, faces east-south-east.

By the time the writer Bowman recorded the site in 1934, it was already in a reduced state. He described it as a double-rampart fort on land belonging to a C. O'Flynn, noting that five-sixths of the outer rampart had been levelled, with only a remnant of about four feet still standing. The 1905 Ordnance Survey six-inch map shows a short stretch of field fence running along the bank from north-north-west to north-east, suggesting the earthwork had been absorbed into the working agricultural landscape long before the twentieth century. Beneath the surface, there may be more to the site still: a possible souterrain has been identified in the interior. A souterrain is an underground stone-lined passage or chamber, commonly associated with ringforts and thought to have served for storage or concealment. Whether this one was ever fully investigated is not recorded.
