San Juan Capistrano is a city in Orange County, California, United States. The current OMB metropolitan designation for San Juan Capistrano and the Orange County area is Santa Ana–Anaheim–Irvine, CA. The population was 34,593 at the 2010 census, up from 33,826 at the 2000 census. The city was created around the Mission San Juan Capistrano, and many of the homes and strip malls resemble the Spanish architecture that composes the building. It is home to the widest variety of homes in Orange County, including those built prior to 1900, in its central district (some being adobes from the 18th century). San Juan Capistrano formerly hosted a population of cliff swallows that migrate each year from Argentina to the Mission San Juan Capistrano.
