It is small, just 2.65 metres in diameter, and consists of only five upright stones, each modest in height, the tallest reaching around 0.8 metres above the ground. Two mature trees have rooted themselves inside the ring over the years, their presence lending the site an accidental, overgrown quality that contrasts with the deliberate geometry beneath them. What makes the circle particularly unusual, even within the already specialised category of Kerry's five-stone circles, is a faint but intentional detail on the axial stone, the smallest of the five, which carries a slight external bevel along its upper surface. The interior ground level is also measurably higher than the surrounding terrain, sitting roughly 0.15 metres above it, suggesting the space may once have been deliberately raised or that it has simply settled differently over millennia.

Five-stone circles are a type of small ceremonial monument found predominantly in south-west Ireland, typically consisting of two portal stones, two flanking stones, and a recumbent axial stone laid flat or nearly so opposite the entrance. The Dromatouk example was documented by Seán Ó Nualláin, the archaeologist who systematically catalogued these monuments across Cork and Kerry during the 1970s and 1980s, with this site appearing in his 1975 and 1984 publications. What distinguishes Dromatouk beyond the circle itself is the density of related prehistoric features clustered around it. Within roughly 250 metres, the landscape holds an anomalous stone group to the north-north-east, a radial-stone cairn to the south-south-west, and a stone row to the east. A radial-stone cairn is a burial monument in which stones are arranged outward from a central point like the spokes of a wheel. The stone row, a linear arrangement of standing stones, adds a further ceremonial dimension. Together, these features suggest that this patch of south Kerry farmland was once a purposefully organised ritual landscape rather than a scattering of isolated monuments.
