It measures roughly forty metres across, its outline subcircular rather than perfectly round, and it sits quietly on a NNE-SSW ridge without any obvious marker or signage to announce what it is. A rath, or ringfort, is an enclosed farmstead, typically of early medieval date, defined by one or more earthen banks and ditches. Thousands of them survive across Ireland in varying states of preservation, and this one in Turlough is among the more understated examples, its bank worn low enough that aerial photography tells the story more clearly than the ground does.

The site first came to official attention in September 2020, when Ros Ó Maoldúin brought it to the notice of the National Monuments Service. Its identification relied on orthophotography captured between 2013 and 2018, in which the subcircular enclosure resolves clearly against the surrounding pasture. A field bank running roughly NNW-SSW cuts across the western sector of the monument, a reminder of how later agricultural boundaries have repeatedly overlaid and interrupted earlier ones across the Irish landscape, sometimes preserving ancient earthworks by accident, sometimes complicating their interpretation.
