It rises only about one and a half metres above the surrounding ground, its sides sloping so gently that they blend into the natural contours of the rise beneath it. Yet the flat top, measuring roughly eleven by ten metres, gives it away: this is a deliberately shaped thing, not a trick of the landscape.

What makes the site quietly puzzling is how it appears, and then disappears, from the historical record. The first edition Ordnance Survey six-inch map of 1838 marks a small circular enclosure at this location, with a diameter of around ten metres, suggesting that surveyors at the time recognised something worth recording. Later map editions omit it entirely. The mound itself, when measured on the ground, is considerably larger than that early depiction, running approximately twenty-five metres north to south and twenty-one metres east to west. Whether the 1838 surveyors captured only a partial or already-degraded feature, or whether the later cartographers simply chose to leave it out, is not clear. To the west, the ground opens onto a flat expanse of bog. To the south-east, a spring feeds into a small pool sitting in a natural dip, beyond which the land rises again to a low ridge. The combination of a water source, elevated ground, and a constructed flat-topped mound is a pattern that recurs across the Irish landscape in contexts ranging from early medieval assembly sites to burial monuments, though what purpose this particular example served remains unestablished.
