Tucked behind the old school on the island’s northern side, this enigmatic feature consists of upright stone slabs, each standing roughly 0.75 metres tall, arranged to form two sides of a square measuring approximately four metres on each side. The third wall is naturally formed by the rock outcrop it adjoins, whilst the fourth side remains open, creating a partially enclosed space that has captured local imagination for generations.

Within this stone enclosure, two flat slabs lie horizontally against the western wall; these are known locally as the Mass Rock, suggesting the site may have served as a clandestine place of worship during the Penal Laws when Catholic mass was forbidden. Such Mass Rocks are scattered throughout Ireland, silent witnesses to a time when religious practice was driven underground. The site once held another curious feature: a flat stone bearing a depression resembling a bullaun, those mysterious bowl-shaped hollows carved into rocks that are found at many early Irish Christian sites, though this particular stone appears to have vanished from the enclosure.

The exact purpose and age of ‘The Grave’ remain uncertain, though its combination of features hints at layers of use and meaning accumulated over centuries. Whether it served as a burial site, a place of worship, or held some other significance to the island’s small community, it stands as a testament to the rich archaeological heritage of County Donegal’s remote corners, where ancient stones hold stories we can only partially decipher.
