Drum Castle features a 13th-century castle keep that’s the oldest intact example in Scotland. Besides the hidden toilet, the team found a second secret chamber that’s reputed to have been where one of the men of the clan hid out for three years after the defeat at the Battle of Culloden. The chamber with the toilet was hidden by bookshelves installed in the 19th century, while the second chamber was a real-life safe room for rebellious Scots. Both were found in the medieval keep.
From 1323-1975, Drum Castle was the seat of the Chief of Clan Irvine. In addition to the keep, the property features Jacobean and Victorian additions. It is now open to visitors and is only 10 miles outside Aberdeen. Visitors can see the historic interior and stroll through the surrounding ancient oak woodland, a rare survival of primeval forest that’s been designated a Site of Special Scientific Interest.
