The remains at Coogue are modest, totalling around three metres in length along a roughly north-east to south-west axis, yet they sit on elevated ground with wide views to the north-east and south-west, a siting choice that feels deliberate rather than incidental. Two parallel side stones stand approximately 1.4 metres apart; the northern of the two is more deeply embedded and leans outward. A third stone, positioned slightly to the east, is thought to be an end stone and tilts gently to the north-east. The interior area between them is slightly raised, grassy, and scattered with smaller stones, suggesting the ghost of a chamber that time has largely consumed.

What makes this site quietly puzzling is its absence from the Ordnance Survey six-inch maps of both 1838 and 1917. Those surveys were reasonably thorough in recording antiquities, so the omission suggests the tomb was either too ruinous to be noticed by cartographers, or that its three stumps were simply read as field stones rather than the remnants of a structured monument. The site does not stand alone in the landscape, however. Within a few hundred metres, there is a ring barrow, a circular earthwork enclosing a burial, 200 metres to the south-west, and a rath, an enclosed farmstead of the early medieval period, 140 metres to the south-east. To the north-east, at around 290 metres, lies a court tomb and an associated cist, a small stone-lined grave box. This clustering of monuments spanning different periods points to a stretch of ground that communities returned to, and marked, across several thousand years.
