This lone 5’8” stone is said to have once been part of a stone circle. The other 10 or 11 stones were removed c.1835, according to the 1905 source mentioned in the Canmore record. It was also said that the surviving stone originally had projections from two edges so that it resembled a cross. They were supposedly knocked off when the circle was destroyed. This tradition was collected in the 1930s (and was still known in the late 60s) – it seems quite a strange idea? The stone does have a kind of ‘waist’.
