Tantallon Castle in Scotland.
Tantallon Castle served as a great baronial residence for the Douglas family for 300 years.
The castle was built in the 1350's by William, 1st earl of Douglas, who had inherited the barony of North Berwick from his uncle, Sir James of Douglas, a close friend of Robert the Bruce. Following the death of his son James, the house heirless was divided in two with Tantallon passed to the 'Red' Douglases, earls of Angus.
The castle survived two siege attempts.
