This is a ring barrow, a type of prehistoric funerary monument consisting of a central mound enclosed by a surrounding ditch, known as a fosse, and an outer earthen bank. What makes this particular example worth pausing over is the degree to which later human activity has layered itself onto the prehistoric fabric, turning it into something more complicated than a simple burial mound.

The mound itself is roughly thirty metres across at its base, rising from about eighty centimetres on the western side to one point four metres at the south. Around it runs a flat-bottomed fosse up to eleven metres wide, and beyond that an outer bank that varies from six to twelve metres in width depending on where you measure. So far, so typical for a monument of this class. But at some point the fosse was re-cut and converted into a drainage channel, its base widened and a secondary exit drain cut toward the south, suggesting that whoever farmed this land later found the ancient earthwork a convenient feature to press into practical service. More striking still is the presence of an entrance gap seven metres wide through the bank on the eastern side, accompanied by a causeway of the same width leading up onto the mound itself. That causeway connects to a subrectangular hut site sitting directly on the mound, a later structure occupying one of the older ones in a way that was not uncommon in early medieval Ireland, when prehistoric monuments were reused as settlement sites, boundary markers, or meeting places. A separate modern entrance has been cut through the bank on the north-western side, adding one more layer to the monument's long afterlife as a working part of the landscape.
