Megalithic tomb - portal tomb, Srath Bruithne Uachtarach, Co. Donegal

The tomb sits within an area of cut-away bog, where centuries of turf cutting have left their mark on the landscape. Just over a kilometre downslope to the south-southwest, you’ll find a stone circle, placing this monument within a broader prehistoric landscape that speaks to the ritual importance of this region during the Neolithic period.

The tomb itself, aligned roughly north-northeast to south-southwest and measuring at least 2.6 metres in length, stands at the northern end of a partially robbed stone cairn that originally measured nearly 11 metres long and 8 metres wide. The monument was likely exposed during the 18th or 19th century when locals were cutting turf in the area, and evidence suggests parts of the western side were later rebuilt, possibly to create a makeshift shelter. The chamber’s entrance features two portal stones flanking a central sill stone; the western portal stands 1.15 metres high, whilst its eastern companion has been damaged and now reaches only 0.65 metres. Behind each portal stone, single orthostats form the chamber’s sides, both leaning inward to support a roofstone that covers the inner portion of the chamber.



What makes this tomb particularly interesting is its deliberate architectural design, with the structure decreasing in height from front to rear; the roofstone sits 0.60 metres above the floor at the entrance but slopes down to nearly floor level at the back. A large displaced slab lying immediately in front of the chamber appears to be the original front roofstone that would have completed the structure, resting on both the portal stones and the surviving roofstone. Today, the chamber floor floods in wet weather and is strewn with stones from the disturbed cairn, but the monument remains an impressive testament to the engineering skills and ritual beliefs of Ireland’s earliest farming communities.
