Greadal Fhinn is a Neolithic chambered cairn which lies on a knoll behind Ormsaigmore, to the west of Kilchoan, in Ardnamurchan. This circular structure may originally have been covered by loose rocks that have been scavenged for use in buildings but today a pair of burial chambers are exposed; a cist grave and a passage grave. It is thought that upright stones once surrounded the monument, which is approximately 22m / 72 feet in diameter.
Greadal Fhinn is referred to as a 'Druidical Circle' or 'Stone Circle' on early Ordnance Survey maps and is still known locally as "the standing stones". Despite this being established as a Neolithic monument, folklore suggests that it was the burial place of the Viking leader Keitell Flatnefr of Raumsal, also known as Caithil Fin.
