Casa Grande is a dynamic, involved community, 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 20 miles to the northeast. Midway between Phoenix and Tucson, the city has grown to be the largest community in western Pinal County since its incorporation in 1915.
