This is Tucson's main venue for the performing arts, home of the Tucson Symphony Orchestra and the Arizona Opera, as well as the locale for pop music concerts, sports events and major trade conventions. A result of 1970s style urban renewal, it is only somewhat interesting stylistically compared to the old adobe buildings that were bulldozed to make room for what now stands. However, some abstract sculptures and fountains outside the complex provide food for the art lover's imagination. There are three performance venues - Tucson Arena, Tucson Music Hall, and the Leo Rich Theater, as well as a number of Ballrooms. Every February the Center hosts the preeminent Tucson Gem and Mineral Show.
