“East Lothian has a rather dubious reputation for having had a large number of witch trials in the sixteenth and seventeenth centuries. Spott was one of the centres of accusations in 1662. The stone is said to be near where Marion Lillie, the Ringwoodie Witch, was executed, reportedly in 1698. One story is that she was the last of those accused of witchcraft to be burnt in Scotland, but this is unlikely to be true as there are (unfortunately) later stories from Dornoch and Crieff. Recent reports have coins, candle wax, and the remains of incense being found at the stone.”
