As the fourth incorporated city in Los Angeles County, Monrovia has more than 125 years of architectural heritage reflecting the diverse styles seen in Southern California. When Monrovia was established, Queen Anne Revival of the Victorian era was the common style, and Midtown Monrovia still has several homes dating to the city's incorporation in 1887. Around the turn of the twentieth century, housing was moving away from Victorian influence before a new dominant style had emerged, and American Foursquare and Victorian Transitional became popular. Transitional styles showed early Craftsman influences and were considered a little bit Victorian and a little bit Arts and Crafts. In the 1920s, motion pictures became one of America's primary forms of entertainment, and movie sets introduced audiences to building styles from different eras, helping spur an eclectic architectural period that included Colonial, Spanish, and Tudor Revivals.
