Why Casa Grande Ruins National Monument is Well Worth the Visit

History of how Casa Grande Ruins was formed

Casa Grande Ruins is one of the largest existing historic structures in North America. But, its’ purpose remains question.

More than 650 years ago, the Casa Grande region was an incredibly fertile region in southern Arizona.  

The Ancestral Sonoran Desert People deemed it as their farming community because of the location’s water sources that led to them building irrigation canals. 

Through years of extensive research, archeologists conclude that the Ancestral Sonoran Desert People built their community due to the location’s rich fertile soils and the abundance of water sources.

The natives painstakingly hand-dug an impressive Hohokam irrigation canal system that would aid in sustaining their farming and artistic livelihoods.

The Ancestral Sonoran Desert People would erect earthen buildings and walls; creating their own compound that lasted for centuries. And small remnants of those walls and structures remain today.

Also known as the Hohokam Indians, they dressed very simple using animal hides and woven fibers from plants for their breechcloths.

In the winter, they dressed in heavier buckskins, woven blankets and cloths. And because of the desert terrain, they made sandals to protect their feet.

The Hohokams were farmers; growing cotton, beans, squash and corn.

But the Ancestral Sonoran Desert People were amazing artists and craftsmen. The local crafters would handcraft pottery out of the Tucson Basin clay. They would mine for minerals to grind pigments into a fine powder to make their slips and paint.

However, it still remains unclear why the Ancestral Sonoran Desert People tribe up and left the region.

There is evidence that a drought period forced them disperse and relocate. Which explains why the structures were left to abandonment.

Since there’s no written records or evidence of their evacuation, scientists and historians estimate the Ancestral Sonoran Desert People left Casa Grande about 1450 C.E.

Today, all that remains are the Casa Grande Ruins.

Casa Grande Ruins RE-Discovered

In the late 1600’s, Padre Eusebio Francisco Kino happened upon the Casa Grande ruins. In his travel journal, he describes the remaining large ancient structure as Casa Grande, Spanish for great house.

Once word got out about his findings, visitors flocked to explore the region including Lieutenant Colonel Juan Bautista de Anza, who set out on his own expedition to find it.

Then, three quarters of a century later in 1846, a military detachment led by Brigadier General Stephen Watts Kearny came upon the Ruins. 

After several prominent explores made their own discoveries, it didn’t take long after for the word to get out.

Public interest and visitors began to check it out for themselves. But, this ended up becoming a double-edge sword.

✰ CASA GRANDE RUINS FUN FACT   In 1833, Brigadier General Stephen Watts Kearny was deemed Father of the United States Cavalry.

Casa Grande Ruins abandoned and vandalized

By the 1880’s, because of the nearby railroad construction twenty miles afar and stagecoach route, mindless visitors took to desecrating the Ruins. Visitors dug up artifacts. And for jollies, they carved their names or messages into the red adobe structures.

They surely didn’t follow the leave no trace principles.

This became a serious cause for concern. A few short years later, traveling historian and anthropologist Adolph Bandelier wore in his journal of what he saw; reporting his displeasure of his findings.

Because of that, a group of prominent Bostonians stepped forward to preserve this important historical site.

A petition was sent before the U.S. Senate in 1889 requesting protection and preservation of the Casa Grande Ruins.

Under the Presidency of Benjamin Harrison, repair and restoration of the Ruins was established. This was the U.S. government’s first cultural reserve and prehistoric restoration.

Casa Grande Ruins becomes a National Monument

In 1901, restoration was in full order and the management and overseeing the project was transferred to the General Land Office. Two years later, a roof structure was built directly over the big house structure to protect it from the weather elements. Major repairs and excavation would continue.

Then, in 1918, President Woodrow Wilson put in a proclamation deeming Casa Grande Ruins a National Monument. It was was then, transferred to the National Park Service for preservation management and education.

Since the inception of this incredible preservation of what the Ancestral Sonora Desert People left behind, multiple restoration projects continue.

In the 1930’s and 1940’s, adobe buildings to support the monument park were built by the Civilian Conservation Corps. Now listed in the National Register of Historic Places, they remain today and little has changed since then.

The visitor center building and a newer steel shelter roof over the Casa Grande Ruins Great House was erected to protect the ruins. Roads and walkways were paved and beautification projects began.

Drawing less than 70,000 visitors annually, Casa Grande Ruins National Monument continues to decline in visitation numbers. That could be, in part, due to its’ remote location.

But, the National Park Service continues their research, interpretive programs and preservation of the Ruins and grounds for present and future generations to enjoy and learn. Scientists, Archeologists and Anthropologists continue their studies, collecting artifacts and cataloging their finds.

But Casa Grande Ruins National Monument isn’t just about the Ruins and the People who once inhabited the region.
