On the fourth day of our trip to Tucson, we visited Old Tucson Studios. An old movie studio where many of the old westerns were filmed. “Old Tucson was originally built in 1939 by Columbia Pictures on a Pima County-owned site as a replica of 1860s’ era Tucson for the movie Arizona (1940), starring William Holden and Jean Arthur. Workers built more than 50 buildings in 40 days. Many of those structures are still standing.”, Wikipedia
