Orange County contains some of the best-maintained and -restored examples of Mission Revival architecture in the United States. The best example of this style is San Juan Capistrano's Los Rios Historic District, which also happens to be the oldest continually-occupied residential neighborhood in the state - and one of the oldest in the country. Montanez Adobe (which some folks say is haunted), built in 1794, is open for tours, and the area's other historic adobes are lived in to this day - the 10th generation of the Rios family lives in one of them. The O'Neill Museum is also worth a visit when you are in the area. A number of small shops, galleries and restaurants fill the 18th and 19th century wooden homes of Los Rios; take a walking tour of the area and explore at your own pace.
