The ringfort at Eskerboy, in Co. Galway, survives only partially, its arc of earth and stone visible from the south-southwest around through the west to the northeast, while the rest of the circuit leaves no trace on the surface at all. What remains is a circular rath, a type of enclosed farmstead typically built during the early medieval period, roughly the fifth to twelfth centuries, when such enclosures served as the principal unit of rural settlement across Ireland. This one measured approximately 33 metres in diameter, modest but not unusual for the form.

The surviving bank is composed of earth and stone, and several breaches in it appear to be of modern rather than ancient origin, the kind of gradual attrition that comes from centuries of agricultural use, animal movement, and the quiet pragmatism of farmers who needed gaps where none existed before. The road that now crosses the monument from southwest to east represents a more deliberate intrusion, slicing through the old enclosure and leaving the two halves on either side to weather at their own pace. Set in gently undulating pastureland, the site is the sort that rewards patience and a certain willingness to read a landscape in fragments rather than as a whole.
