San Juan Capistrano (/sænˌwɑːnkæpɨˈstrɑːnoʊ/; Spanish: [saŋ ˈxwaŋ kapisˈtɾano]) is a city in southern Orange County, California, located approximately 23 miles (37 km) southeast of Downtown Santa Ana. 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 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), a number of 10-million-dollar homes in the gated communities of the hills, and working ranches in its foothills. San Juan Capistrano formerly hosted a population of cliff swallows that reputedly migrate each year from Argentina to the Mission San Juan Capistrano.
