Canterbury Castle, also known as Arlington Castle, was a private house located in southwest Portland, Oregon listed on the National Register of Historic Places. Constructed during 1929–1931, the house was designed by Jeter O. Frye to resemble England's Canterbury Castle on the exterior and to evoke the Art Deco styling of Hollywood of the 1920s on the interior. The house included castle features such as a moat, drawbridge and turret and attracted paying tourists immediately following its completion. Canterbury Castle, Portland's only 1930s castle structure, was added to the National Register of Historic Places in 1987. The house underwent major renovation efforts in the 2000s without completion and was demolished in 2009 after failing to meet municipal safety codes. The razing of Canterbury made Piggott's Castle the city's only remaining castle. Canterbury Castle was removed from the National Register of Historic Places in October 2010. The property was also designated as a Portland Historic Landmark.
