Holydean Castle (pronounced "hollydeen") was a castle sited near Kelso in Bowden, 1.25 miles SW of the village, in the Scottish Borders region of Scotland, and the former Roxburghshire. The castle was founded by King David I. It was destroyed in 1276, rebuilt in 1530 by Dame Ker, and destroyed again by the 3rd Duke of Roxburghe in 1760. Very little of it now remains. This Norman castle was named after the Lords Holydean, who were originally the deans of Kelso Abbey: monks who held great power in what was one of the largest feudal territories and most profitable regions of Scotland. The peerage title, barony, and castle eventually went to the Kerrs who were made Earls of Roxburghe, and later Dukes.
