The recumbent stone circle (RSC) at Cothiemuir Hill is also known as ‘Devil's Hoofmark’ because of the shell marks on the recumbent stone. The circle encloses a well-preserved cairn and originally consisted of up to thirteen stones, but now only eight. The large recumbent stone and the flanks are particularly impressive. The horizontal stone is said to weigh over 20 tonnes and the flanks are around 2.70 m high. The circle has a diameter of around 20 metres and was probably erected over 4,000 years ago on the site of an earlier burial mound with a central chamber.
