Casa Grande Ruins National Monument located in Arizona preserves Hohokam Culture and ruins of the largest prehistoric structures ever built in North America. It is hard to believe that the Great House has survived the heat and dryness of the desert for so long.
Casa Grande means Great House and that truly is what it was in years past. It is believed that the great house was completed in 1350. Years of souvenir hunters and visitors damaged the site until in 1892 Casa Grande became the nation’s first archeological reserve.
Be prepared for hot dry weather during your visit to Casa Grande. There is some shade from the roofs protecting the structure but it is still super hot depending on the time of year you visit. There is a grocery store right across the street that is great for picking up water and snacks.
There is a shaded picnic area within the park that you can use to enjoy a break from the sun. The visitor center is filled with great interpretive information and museum pieces. Make sure and check out the park movie Casa Grande: House of Many Stories for a great look at what life was like at Casa Grande.
Give yourself at least an hour to visit the park and explore the ruins. I would highly suggest going early in the morning if possible to miss the heat of the day.
Casa Grande National Monument
The ruins of Casa Grande have been written about by explorers as long ago as the 17th century. Built by Sonoran desert people who have come to be called the Hohokam.
At the height of the Hohokam civilization, they established trade routes, dug hundreds of miles of wide-scale irrigation farming canals for their crops, created jewelry and pottery, and used natural soil material called caliche to erect buildings like Casa Grande.
The Hohokam began to abandon their structures around 1450 C.E. It is still unclear why they started to abandon their structures but it is speculated it was due to drought, invasions by other tribes, disease, floods or intra-tribal strife.
