At Ballymacpierce, a ringfort sits on a gentle south-facing slope in pasture, and within roughly a hundred metres to its south lie two further earthworks: a ring ditch and another ringfort. That kind of density, three related features within a short walk of one another, suggests this was once a purposefully settled landscape rather than an isolated farmstead.

The site itself is a rath, the Irish term for an earthen ringfort, the most common type of monument surviving in the Irish countryside. Roughly circular and about 45 metres in diameter, it is defined by two concentric earthen banks separated by a fosse, which is simply a ditch cut between them. The inner bank still rises about 0.6 metres on its interior face; the outer is a little lower at 0.4 metres. These are modest dimensions, though centuries of weathering and the encroachment of vegetation will have reduced them considerably. Writing in 1934, a researcher named Bowman noted that the interior of the site is saucer-shaped, dipping gently toward its centre, which is a feature sometimes associated with earlier activity beneath or within the enclosure. The site is heavily overgrown today, and the earthworks are likely easier to read from outside the vegetation than from within it.
