Bank One Building, Tucson

Built in 1929, this building has the distinction of being Tucson's first skyscraper, towering high over the one-level houses that gave Tucson its distinct Western town character. From 1935 well into the 1990s, it was known as the Valley National Bank Building until another, bigger corporation took over. Today, higher structures dominate the Tucson skyline, but this particular building, apart from its historic impact, still derives some charm from the tree-shaded brick patio on its south side, which is always welcome in the brutal Tucson summer. Visitors may enjoy free access to the lobby during business hours.
