Canterbury Castle, Historical villa in Arlington Heights, Portland, United States

Canterbury Castle was a 6,000-square-foot, three-story house in Arlington Heights near Washington Park, with views of downtown Portland. It was built of basalt quarried at Rocky Butte, with a seven-foot-wide moat crossed by a wooden drawbridge and a copper-clad turret. The concrete foundation carried a rectangular plan; the interior was arranged around a central stair tower with a conical copper roof.

Jeter O. Frye designed the house and built it between 1929 and 1931. Unable to sell it, he left Portland bankrupt, but tourists soon paid to tour the castle. It joined the National Register of Historic Places in 1987 under Dale and Karen Bernards and was later named a Portland Historic Landmark. After failed 2000s renovations, it was demolished in 2009 and removed from the register in October 2010.

The name Canterbury Castle came from the plat and the street where the house stood, not from England's cathedral city. After completion in 1931, the house drew paying tourists and school groups, became a stop on the Washington Park bus tour, and hosted Halloween parties for a local radio station.

The house was demolished in 2009 after failing to meet municipal safety codes, so there is no entry or interior to visit. The site is on a hillside in Arlington Heights near Washington Park; the single-car garage was built into the slope. Look for the address and street name that gave the house its name.

The house was a stop on the Washington Park bus tour and hosted Halloween parties for a local radio station. Its basement pool was eventually closed because of water leaks, and one bathroom was modeled on Charlie Chaplin's.
