Ringforts, the circular enclosures that were the dominant form of rural settlement in early medieval Ireland, typically survive as earthworks in open farmland or on hillsides. This one has not been so fortunate, or perhaps so conspicuous. The enclosure is still there, technically, but the house and its grounds now occupy the interior, making the monument one of those awkward cases where archaeology and the everyday have become thoroughly entangled.

The site appears on the Ordnance Survey six-inch maps of both 1843 and 1937, marked each time as a hachured enclosure, the cartographic shorthand for a raised or banked feature visible from the ground. A sketch map accompanying the OS Memoranda, compiled by O'Flanagan in 1927, names it "beanna fort," suggesting local knowledge of the site persisted well into the twentieth century. When Healy examined it between 1975 and 1979, the ringfort could still be read as a ring feature with an external diameter of approximately 28 metres, defined by a bank of stones enclosing a level interior. That roughly 28-metre spread is on the smaller end for a ringfort, consistent with a single-family farmstead of the early medieval period, though nothing in the available record tells us who built it or when it was abandoned.

The site is not publicly accessible, sitting as it does within private residential property. What makes it worth knowing about is less any prospect of a visit and more what it illustrates about the fate of monuments in suburban and peri-urban Dublin. The Rathmichael area retains a number of early medieval and earlier remains, and the broader hill repays careful map-reading before any walk in the area. The 1843 OS map, freely available through the OSi historical viewer online, is the clearest way to trace what the enclosure once looked like in the landscape before the bungalow arrived.
