Casa Grande is a modern city with rural heritage and old-fashioned values. Its economic base is a mix of retail trade, factory outlet shopping, manufacturing and agriculture. Founded in 1879, Casa Grande was named for the famous Hohokam Indian Ruins located 20 miles to the northeast. Midway between Phoenix and Tucson, the city has grown to be the largest community in western Pinal county. Nearby attractions: Casa Grande Ruins National Monument features 60 prehistoric Hohokam sites. Casa Grande is home of two factory-outlet centers featuring 50 upscale fashion designer and national manufacturers' stores in both the Tanger Outlet Center and Factory Stores of America. Both centers are located along Interstate 10
