They are grassy, earthen, and quiet, the kind of feature that reads at first glance as a natural swelling in the land. But their dimensions are too regular for accident, and their pairing is too deliberate to ignore.

The southern mound measures roughly 15.8 metres east to west and just over a metre in height; the northern is somewhat smaller, at 10.8 metres along the same axis. Both are composed of earth and stone. When a researcher named Mac Domhnaill documented them in 1933, drawing on fieldwork for what was then the National Museum of Ireland's topographical files, he classified them as partly disturbed twin grave mounds. Grave mounds of this kind are burial monuments, raised over interments and sometimes enclosed by kerbing or revetment walls, the possible stone facing visible between these two mounds hinting at something more structured than simple earthen heaping. The disturbance Mac Domhnaill noted suggests the site had already been interfered with before the twentieth century, whether through agricultural activity, casual digging, or earlier antiquarian curiosity.
