La Casa Cordova
175 N. Meyer Ave.
Continuously inhabited by Mexican American families from 1848 until it became part of the Tucson Museum of Art Historic Block in the 1970s, this house is named for its last resident, Maria Navarette Cordova. Now a Mexican heritage museum, its five rooms have been restored to their original style. If you're curious about what the original Spanish garrison looked like, a small replica is displayed here. The best time to visit La Casa Cordova is between late November and early March; that's when Maria Luisa Teña's elaborate folk-art nacimientos, or nativity scenes, are shown. You get in free with paid admission to the Tucson Museum of Art.
