Canmore describes how there was a fort covering the summit of this hill - only the south side is easily approached because the other sides are so steep. It's just over 200m NNE of the parish church, where there was once a stone:
A large stone, popularly called the "Witches' Stone," stood upright, near the church, in a field on Lodge-house farm.* The tradition is that a witch flying with it, to demolish Craigie Kirk, her apron strings gave way, and it fell down on the spot which it afterwards occupied. It was in all probability a druidical remain; probably a rocking-stone. It stood upon three stones, so high that a man could crawl under. It was destroyed in 1819, to build houses. The farmer's wife, it is said, took some antipathy to it, and would not give her husband rest until he consented to have it removed. A person of the name of Jamieson, and an assistant, were employed to blast it, which was accordingly done. When broken up, it filled twenty-four carts. Such was the feeling of sacrilege occasiioned by the removal of the stone, that it was observed the farmer's wife became blind, and continued so for eight years, when she died. Jamieson, who blasted it, never did well afterwards. He drank and went to ruin.
Further warning not to Mess With Stones.
*Now called Lodgebush, according to the Canmore record.
Also, the source of this ('History of the County of Ayr' by James Paterson, 1847) next says:During the era of smuggling, Craigie hills are known to have been the depository of a large share of the contraband goods landed at Troon and other parts of the coast. The broken nature of the crags afforded many secure places of secrecy. The old worthies who took part in this exciting trade have scarcely yet all died out.
