This one in Annaghard, County Cavan, offers something considerably more modest: a slight raising of the earth roughly 26.8 metres across, and a kink in a field boundary running from north to east to south. That small deflection in the hedgeline is, in essence, all that physically remains of what local tradition holds to be the site of a fort.

A ringfort, or rath, was typically an enclosed farmstead of the early medieval period, its circular bank and ditch serving as a boundary marker and a modest defence for the household within. Here, on the summit of a drumlin hill, one of those rounded glacially deposited ridges that give this part of Cavan its corrugated landscape, the enclosure would have commanded a decent view of the surrounding terrain. Ordnance Survey maps from 1836 and again from 1876 record the area as a small, subtriangular field, a shape that may itself reflect the lingering outline of an earlier boundary. By the time those maps were being drawn, whatever earthwork once defined the perimeter had already been reduced to the faintest of traces.

What survives now is the kind of site that rewards patient attention to landscape rather than dramatic discovery. The slightly raised ground, the anomalous angle in the field boundary, and the hilltop position together make a coherent, if understated, case for something having been deliberately placed here long ago.
