Ethie Castle is a 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. The castle was purchased in 1665 by the Carnegie family, who later became the Earls of Northesk, and was owned by them through to 1928 until it was bought by William Cunningham Hector. The castle is reputed to be the basis for the fictional Castle of Knockwhinnock in Sir Walter Scott's novel The Antiquary . Sir Walter Scott was a close friend of William Carnegie, 8th Earl of Northesk and frequently stayed at Ethie Castle. The castle was restored by the chief of the Forsyth Clan, Alistair Forsyth and it now serves as the clan's seat. The castle is presently owned, however, by the de Morgan family and has been converted for use as a hotel.
