Sun City, Arizona, the nation's first master-planned, active-adult retirement community, reinvented the definition of "retirement living" when it opened its doors in 1960. Located 14 miles northwest of Phoenix, this community was cultivated from the dusty desert cotton fields once known as Marinette Ranch. Developed by master builder Del E. Webb, Sun City combined affordable housing with recreational amenities to create a lifestyle designed to rejuvenate the body and keep the mind and spirit feeling forever young. Sun City's success gave birth to an entirely new industry catering to older Americans. The famous "Sun City Lifestyle" remains as popular today as it was in 1960.
