Popularly known as St Columba's Pillow, this water-worn boulder with a ringed cross carved onto it was found by a crofter in 1870 at Clanh an Dìsirt (about a kilometer NE of Iona abbey). Frustrated that his cartwheel constantly hit the stone, he dug it up. It became known as ‘Columba’s Pillow’ – the stone that St Columba laid his head each night and which after his death marked his grave. There is no evidence to support this identification and it seems unlikely that Columba would have been buried so far from the abbey. Nonetheless the stone became so famous that in the early 1900s that it was enclosed in a metal cage for safe-keeping.
