Megalithic tomb, Tullynabratilly, Co. Donegal
On the southern slopes of Coolcross Hill in Tullynabratilly, County Donegal, there once stood an enigmatic stone structure known locally as 'Grania's Bed' or 'Dermot and Grania's Bed', names that evoke the legendary lovers of Irish mythology.
Megalithic tomb, Tullynabratilly, Co. Donegal
First recorded on Ordnance Survey maps in 1834, this mysterious monument survived until sometime before 1945, when it vanished from the landscape entirely, leaving only written accounts of its existence.
The few descriptions that survive paint a picture of what might have been a megalithic chamber grave, though certainty remains elusive. When surveyed at the turn of the 20th century, it was recorded simply as ‘an antiquity consisting of a few stones forming a rectangle’. By 1929, antiquarian Boyle Somerville provided more detail, describing three stone slabs set on edge into the ground, running parallel to each other about 1.5 metres apart. Each slab stood roughly 1.8 metres long and rose about 0.9 metres above ground level, marking what appeared to be the sides of an ancient burial chamber. The capstone that would have covered the structure, along with any other original features, had long since disappeared.
Whilst the romantic name and stone arrangement suggest this may have been a prehistoric tomb, possibly dating back thousands of years to Ireland’s Neolithic period, the limited evidence makes it impossible to classify with confidence. The site now exists only in historical records and surveys, a reminder of how many ancient monuments have been lost to time, agriculture, and development across the Irish countryside. Its inclusion in various archaeological surveys from Borlase in 1897 through to the Record of Monuments and Places in 1995 ensures that, whilst the stones themselves are gone, the memory of this curious feature endures.
