Easy to overlook, easier still to mistake for a natural feature of the ground, the ring barrow at Bunnafedia is one of those sites whose significance is entirely out of proportion to its physical presence.

A ring barrow is a funerary monument, typically from the Bronze Age, consisting of a central mound or platform enclosed by a circular bank and an inner ditch, known as a fosse. At Bunnafedia, the raised circular area measures 6.6 metres in diameter, ringed by a bank of earth and stone between 2.5 and 2.8 metres wide and just 0.4 metres high. Inside that bank, a fosse roughly 1.7 metres wide and 0.3 metres deep separates the bank from the central area. The whole structure is modest in scale but precise in form, and the interior fosse is a characteristic detail that distinguishes ring barrows from other related monument types. What cannot now be determined is where the original entrance once lay; any gap or causeway that may have allowed access to the enclosed space has long since been obscured by time and the slow creep of the surrounding pasture.
