Tucson has been continuously settled for over 12,000 years. It celebrates a diversity of cultures, architecture, and peoples. Yet, it is one of the “Mega-Trend” cities of the 21st Century: the Optics Valley, premier health services center for the Southwest, the astronomy center of the world, home of a premier research institution – University of Arizona, and a tourism destination.
