Dermot and Gráinia's Bed is a wedge tomb located near Strabane in County Tyrone, Northern Ireland. This megalithic monument dates to the Neolithic or Bronze Age and belongs to a distinctive class of passage graves found predominantly in Ireland and western Britain. The tomb's vernacular name derives from Irish mythology, reflecting the local cultural memory of the site across centuries. It is protected by the Historic Environment Division under reference 14019.
The monument sits upon bedrock of the Argyll Group, a Neoproterozoic formation comprising psammite, semipelite and pelite—metamorphic rocks that shape the underlying geology of this region. These ancient sedimentary deposits, metamorphosed over geological time, would have presented significant challenges to the tomb's builders, who worked without metal tools to shape and position the massive stone blocks characteristic of wedge tombs.
Wedge tombs typically feature a distinctive tapering plan, wider at the entrance and narrowing towards the rear, with a corbelled or capstone roof. They frequently contained multiple burial deposits and were often used for successive interments across generations. Dermot and Gráinia's Bed exemplifies this monumental Bronze Age funerary tradition and remains a significant marker of prehistoric activity in the Strabane landscape.
