Designated as National Monument no. 139 and under state care, the ancient structure has endured centuries of weathering and disturbance, with field stones now heaped around its partially collapsed form.
The tomb originally featured an east-facing chamber approximately 3 metres long, of which several key stones remain visible despite the monument’s deteriorated state. The southern side retains an upright portal stone standing 2 metres high that narrows towards its top, alongside a sidestone that leans against it at 1.1 metres in height. A large prostrate slab measuring 2.7 by 1.8 metres lies to the south; likely the original roofstone, whilst another displaced slab rests against the northern face of the sidestone, possibly once forming the tomb’s northern wall. This overlying slab partially conceals what may be the chamber’s original backstone beneath.
Historical accounts provide fascinating glimpses into the monument’s condition over time. When Thomas Fagan visited in 1847, he found the tomb already in its current ruined state and noted the remains of an enclosed grave at the base of a nearby standing stone, which still towers 2.05 metres high today. Various antiquarians documented the site throughout the 19th century, with one observer in 1890 reporting that the “fine cromlech” was being used as shelter for cattle. The monument’s enduring presence in this remote Donegal landscape continues to draw archaeological interest, having been comprehensively surveyed and catalogued as part of Ireland’s megalithic heritage.
