Architectural Digest is an American monthly magazine founded in 1920. Its principal subjects are interior design and landscaping, rather than pure external architecture. The magazine is published by Condé Nast, which also publishes international editions of Architectural Digest in Italy, China, France, Germany, India, Russia, Spain, Mexico, and Latin America. Architectural Digest also hosts a popular online video series entitled Open Door that gives an in-depth look at the unique homes of various prominent celebrities and public figures.
