Buchanan Castle is near the village of Drymen in Stirlingshire.
The castle was committed by the 4th Duke of Montrose, James Graham and was built around 181852-1858. It was built to replace the nearby Buchanan Auld House which was destroyed by fire in 1852.
The lands were the property of theClan Buchanan until late in the 17th century when they passed onto the Clan Graham. The castle is still the Seat of the Clan Graham.
It was sold, and in 1930 it was used as a hotel.
This was short lived though, as during the Second World War, it was used as a hospital. It had many patients, including Rudolf Hess, who had crashed his plane while on a spy mission.
After the war, it was briefly used as an Army School of Education.
The roof was removed in 1954 in order to save paying taxes and the castle has been left to deteriorate.
There were plans to turn the castle into luxury flats, but the plans were denied.
