The Earl had used the old tower as a prison and the bells were rung to gather together the local people for the 'King's service' or in times of war. Bessie Graham was imprisoned in the Tower in 1649 on a charge of witchcraft. During a disagreement with her neighbour, comments were made by Bessie that onlookers interpreted as a curse. Mrs Rankin died a few weeks later and this was taken as sufficient proof to formally accuse Bessie of being a witch. Alexander Bogs, a Witch Finder, was called in to examine Bessie and his verdict was that she was a witch, in league with the devil. Bessie was taken to Corsehill Moor and burned at the stake.
