Ethie Castle is a 15,091 square feet (1,402.0 m2) 14th-century castle, situated around 3 miles north of the fishing town of Arbroath in Angus, Scotland. Ethie Castle dates to around 1300, when the monks at nearby Arbroath Abbey built a sandstone keep. The castle passed through the hands of the de Maxwell family and into the ownership of Scotland's last Cardinal, David Beaton who was murdered in St. Andrews in 1546. Its association with Cardinal Beaton is still evident as the castle includes a small chapel and the Cardinal's Sitting Room, with its secret staircase to the Great Hall above.
