point at 437 feet above sea level, a circular hollow in the ground is all that announces the presence of something that was once deliberately hidden. The depression, relatively recently formed, is the result of a collapsed souterrain, an underground stone-built passage or chamber typically constructed in early medieval Ireland for storage or refuge. Through the rubble, a small fragment of drystone masonry and part of a lintel stone remain just visible, the last exposed evidence of what was once a carefully engineered underground space.

The souterrain sits within a ringfort, a type of enclosed farmstead common across Ireland from roughly the early Christian period through to the Norman era, formed here by an earthen bank that still traces its circuit around the hilltop. The collapsed section lies inside the bank on the west-south-west side. Some distance to the east, around four metres away, a linear arrangement of four or five formally placed stones may represent another element of the same underground system, perhaps a passage running outward beneath the interior of the fort. A separate shallow depression curving around the north-east and south-east quadrants of the bank's inner edge may also be connected, hinting that the souterrain was more extensive than the single collapse point suggests. Whether the whole underground network is now inaccessible, or simply unexcavated, the surface traces alone suggest considerable original ambition in its construction.

The hillock offers wide views to the east, south-east, and south across the gently rolling Westmeath pasture, a reminder that whoever built and used this place was not hiding from the landscape but keeping watch over it.
