Bonshaw Tower

About

Bonshaw Tower is an oblong tower house, probably dating from the mid-16th century, one mile south of Kirtlebridge, Dumfries and Galloway, Scotland, above the Kirtle Water. It is adjacent to a 19th-century mansion. The tower was one of a number of structures built along the Scottish border in the 1500s as protection against incursions by the English.
