What was once an oval earthwork enclosure, measuring roughly 45 metres east to west and 30 metres north to south, now leaves almost nothing for the eye to catch, just a faint band of different vegetation and a scatter of angular stones where banks and ditches presumably once defined the perimeter.

A ringfort, or rath, is one of the most common monument types in Ireland, a roughly circular or oval enclosure formed by earthen banks, used primarily during the early medieval period as a farmstead or high-status residence. This one, known as Peake or Cruacamoohallee Fort, was recorded on the Ordnance Survey six-inch maps as a legible oval feature, and in 1914 a scholar named Neary catalogued it as a circular earthen fort, assigning it the number 34 in his survey. That Neary could classify it with apparent confidence in 1914 suggests the earthworks were at least partially visible then, which makes its subsequent disappearance from the ground surface all the more telling. Whether gradual agricultural pressure, erosion, or simple time accounts for the loss is not recorded.

What remains is the hilltop position itself, which would have made the site conspicuous and defensible in its original context, and the subtle vegetational trace that sometimes appears over buried earthworks when soil conditions retain enough moisture or organic material to encourage different plant growth. For anyone walking Peak Hill, knowing where to look and what a slight difference in grass colour or texture can signify is the only way this site now announces itself.
