Downtown Tucson has a couple of historic neighborhoods that are described in "Walking Tours". Among the more interesting buildings are those maintained by the Tucson Museum of Art and located on the block surrounding the museum. These restored homes date from 1850 to 1907, and are all built on the former site of the Tucson presidio. A map and brochures are available at the museum's front desk, and October through April, guided tours of the historic block and Corbett House are available (free with museum admission).
The Conley Museum of the West -- Although little more than a room at the back of the Mark Sublette Medicine Man Gallery, 7000 E. Tanque Verde Rd. (tel. 520/722-7798; www.medicinemangallery.com), the Conley Museum of the West packs a lot into a tiny space. You can see not only 19th- and 20th-century pieces by some of the biggest names in Western art, but also Indian artifacts and art, Spanish colonial antiques, and historical maps dating back to 1739. This place is a must for fans of Western art. The museum is open Monday through Saturday from 10am to 5pm and Sunday from 1 to 4pm. Admission is free.
