Dermot and Grania’s Bed

By: Stephanie Kelly

Dermot and Grania’s Bed, also known as Dunnamore, is a megalith located in Cookstown, County of Tyrone, Northern Ireland. This megalith appears to be made up of at least 6 slabs. All of these slabs range in height and width with the largest single stone being approximately 26 feet long.
This megalith was first documented, though briefly, by men of the names Westropp, Borlase and De Valera. In Westropp’s review of the site it appears that he believes it to be nothing more that a split rock. He appeared to be very set in his thinking that Dermot and Grania’s Bed was nothing more than a natural rock formation. Borlase appears to be unsure exactly what this stone formation is and only mentions its existence without giving a cause for it. De Valera and an associate take a difference stance. They stated that the site could be a “roughly built megalithic tomb” but also note that Westropp’s thought of it being a split rock was preferred.
Dunnamore is one of many megaliths that seem to still be a mystery. It does appears that this site has not had much excavation or research done to help determine its place in history. Many feel that this stone formations could date back to the Bronze Age though excavation and research have not been done to accurate date Dunnamore using today’s scientific testing.
