The fruit trees and surrounding hedge have quietly domesticated a site that, a thousand or more years ago, served a very different purpose. There is no visible ditch, no obvious entrance, and little to suggest to a casual visitor that the gently levelled ground beneath the trees is anything other than a convenient patch of land put to agricultural use.

The site is a rath, a type of ringfort common across early medieval Ireland, typically consisting of a circular earthen bank and outer ditch enclosing a farmstead or high-status dwelling. Here, what survives is a circular platform roughly 30.5 metres in diameter, defined by a scarp, a low stepped or sloping edge, about a metre in height. The fosse, the defensive ditch that would normally ring such an enclosure, has either been filled in or eroded beyond recognition, and no original entrance can be identified. The site appears on the 1911 edition of the Ordnance Survey six-inch map as a circular hachured feature, named in gothic lettering simply as "Doonarah", which likely preserves the Irish place-name associated with the fort itself. That it was recorded at all on that edition of the map, rather than earlier ones, may reflect how thoroughly the earthwork had already merged into the working landscape by the late nineteenth century.
