This 400 by 150 metre expanse of rough grazing land holds a secret beneath its sandy surface: the remains of what appears to be an ancient portal tomb. The site offers dramatic views, with mountains stretching from Glengesh Hill to Slievetooey forming the southern skyline, whilst sandhills block the western sea view at the strand’s outer reaches.

The monument’s fragmented state tells a story of both discovery and loss. In 1976, archaeologists excavated a pit in the sand revealing four substantial stones that seemed to form a single chamber measuring roughly 1.8 metres long and 1.3 metres wide. The most distinctive feature was a gabled backstone, 1.6 metres long, leaning against an upright sidestone that stood 1.4 metres high. These stones, along with several displaced orthostats scattered about the pit, suggested the classic configuration of a portal tomb; one of Ireland’s earliest megalithic structures typically dating from the Neolithic period.

By 1984, the excavation pit had been filled and the ground levelled, leaving only two large slabs visible on the surface. What remains today is a far cry from the structure documented in the 1970s, yet these weathered stones continue to mark the presence of an ancient burial site. The tomb’s location on this tidal island, unmarked on any Ordnance Survey maps, adds an element of mystery to an already enigmatic monument, making it one of Donegal’s more elusive archaeological treasures.
