Dundas Castle is a 15th century castle, with substantial 19th century additions by William Burn, near South Queensferry, to the west of Edinburgh. It was the home of the Dundas family. In 1416, James Dundas obtained a license to build a Keep from the first Duke of Albany, with an extension granted in 1436. It was primarily a defensive refuge. Oliver Cromwell is known to have stayed at Dundas Castle around the time of the Battle of Dunbar in 1650.
The modern Dundas Castle was built in 1818 by the renowned architect William Burn. Burn also designed many churches and this influence is visible throughout the building. Burn's designs for the main state rooms allow for huge windows that look out onto lawns and parkland outside. The Dundas family sold the property in 1846, but it remains in private ownership.
