These stone boundaries, known simply as Wall A and Wall B, lie just north of the Farranmacbride Court tomb, weathered down to roughly half a metre in height after centuries of exposure to the Atlantic elements. Wall A stretches for 18 metres in a northwesterly direction before turning west for another 7.5 metres, where it meets a natural rock outcrop and fades into the landscape. Wall B, the longer of the two, emerges from beneath a layer of soft clay and runs for nearly 40 metres towards the north-northeast.

What makes these walls particularly intriguing is their construction method, which becomes apparent about 12.5 metres along Wall B. Here, three carefully positioned stones suggest the original building technique: slab facings filled with a core of loose stones, a method that would have created sturdy, livestock-proof boundaries. Today, both walls consist mainly of small, loose stones measuring just under a metre wide for Wall A and slightly over a metre for Wall B. The structures now sit amid poor pasture land, their stones gradually settling into the boggy ground that characterises much of this remote corner of Donegal.

While it’s impossible to date these field boundaries precisely, their proximity to the Farranmacbride Court tomb hints at a possible connection to the Neolithic farming communities who built such monuments between 4000 and 2500 BCE. These early farmers would have needed field systems to manage their livestock and crops, making it entirely plausible that these humble walls once formed part of Ireland’s earliest agricultural landscape. The walls were first properly documented in the Archaeological Survey of County Donegal in 1983, ensuring their place in the archaeological record of this historically rich region.
