 Muirtoun is marked by Pont, but seems to have been covered by the extended plantations established by Lieutenant-Colonel William Mure.In 1515 Glasgow's Bishop's Castle was rifled by John Mure, Laird of Caldwell during the earliest days of what was to become the Scottish Reformation.The laird besieged with artillery and took the castle, he then "made off with the bishop's principal goods and chattels as fair and legitimate booty."
