What makes it quietly odd is not the ringfort itself, which is unusual enough, but the addition recorded in its north-eastern quadrant: a folly named Lady Margaret's Tower, marked on the 1913 Ordnance Survey six-inch map and now lost in the same dense thicket that swallows the older structure beneath it.

A rath, or ringfort, is an enclosed farmstead of the early medieval period, typically defined by one or more earthen banks and ditches encircling a raised interior. The example at Ballyeeskeen has a roughly circular flat-topped platform about 25 metres across, bounded by a bank of earth and stones roughly 3 metres wide. What gives the site its particular presence is its position. To the south, the platform stands at an external height of around 3.5 metres above the surrounding ground; to the west and north, the natural slope of the ridge takes over, dropping away steeply to a height of 9 to 10 metres. The river lies about 70 metres to the east. Whoever chose this spot understood the landscape. The folly, Lady Margaret's Tower, is a different kind of monument entirely, a later ornamental structure of the sort built in the eighteenth or nineteenth century for aesthetic effect rather than defence or habitation, though who Lady Margaret was and when exactly her tower was built remains unclear from what survives.

The site is now densely covered in trees and overgrowth, which means the earthworks are largely a matter of inference rather than clear visibility at ground level. The combination of an ancient rath with a romantically named folly embedded within it is the kind of layering that tends to get lost when each element is catalogued separately.
