Balvenie Castle is a ruined fortress located one kilometre north of Dufftown in Moray, Scotland, and among the oldest stone castles in Scotland. Built in the 13th century by Alexander 'Black' Comyn, Earl of Buchan, the castle remained strategically important through centuries of Scottish history. It was captured by Robert the Bruce in 1308 and later held by the Black Douglases before becoming an estate of the Earls of Atholl around 1455. By 1550, the Earls constructed a stately Renaissance mansion within the castle walls. Mary, Queen of Scots visited in September 1562. Today, managed by Historic Environment Scotland, the castle is open to visitors seasonally with exhibition displays and visitor facilities.
