Gelston Castle, located near Castle Douglas in Kirkcudbrightshire in Dumfries and Galloway, Scotland, was built by Sir William Douglas of Castle Douglas, who had acquired the lands of Gelston in 1799. However, Sir William Douglas died without issue in 1809 and his property was divided between various nieces and nephews, with Gelston going to the youngest daughter of his brother James, Mathilda Douglas. In 1813 Mathilda married William Maitland, and their family continued to preside over the estate for most of the 19th Century. Gelston then became the property of the Galliers-Pratts who retained the castle for pheasant shooting, and from whom it was requisitioned during World War II. During this time it served as a home for handicapped boys evacuated from Glasgow, before the roof was removed once this use had ceased.
