Mains Castle, also known as Claverhouse Castle or Fintry Castle, is a 16th-century castle located in Dundee, Scotland. Built in 1562 by Sir David Graham, it features a courtyard surrounded by several buildings, including a six-floor tower house. The castle was the seat of the Grahams of Fintry until the 19th century when it was sold to David Erskine. Renovated in the 1980s, Mains Castle now sits in Caird Park overlooking the Dichty valley and is open to the public as a historic site and park.
