Discovered during peat cutting in the 1940s the site at Beaghmore consists of 7 stone circles. All of the rings are associated with cairns and a stone row runs towards these cairns.
It is possible that Neolithic occupation and cultivation preceded the erection of burial cairns and ceremonial circles and alignments: some irregular lines and heaps of boulders resembling field-fences or field-clearance may predate the ritual structures. At some stage peat started to form over the site, and it may conceivably be that the cairns and rows were erected in a futile propitiatory attempt to restore fertility to the soil by attracting back the fading sun.
