Ruthven Barracks outside Kingussie in the Highlands; from Wikipedia:

"Ruthven Barracks near Ruthven in Badenoch, Scotland, are the best preserved of the four barracks built in 1719 after the 1715 Jacobite rising.
Set on an old castle mound, the complex comprises two large three-storey blocks occupying two sides of the enclosure, each with two rooms per floor.
The barracks and enclosing walls were built with loopholes for musket firing, and bastion towers were built at opposite corners.
Destroyed by Jacobites following their retreat after the Battle of Culloden in 1746, the Barracks ruins are maintained as a scheduled monument by Historic Environment Scotland".
