Dumfries and Galloway
It's thought that it was built sometime during the 16th century, and is said to have belonged to the Scottish Regent, James Douglas, 4th Earl of Morton. James Douglas was one of four regents who oversaw Scotland during the early years of James VI's rule. He was famous for introducing the Maiden to Scotland...a Scottish version of the Guillotine. Ironically, he was executed using the maiden in 1581.
The remains of this sorry tower can be seen freely at the road side.
