Casa Grande National Monument 

Casa Grande National Monument - The Casa Grande Ruins were protected as the nation’s first archeological reserve beginning in 1892. The site was declared a National Monument in 1918. The park is one of over 20 National Park Service (NPS) sites you can visit in Arizona, and one of over 400 NPS sites in the United States.

        The Casa Grande (Great House) was built between 1300 and 1400 CE (Current Era). Between 1355 and 1450 CE, the ancestral Sonoran Desert people began to move out of their walled compounds and villages. Archeologists do not know all the reasons for the dispersal of the people from large walled communities to other areas and smaller communities.
