Casa Grande Ruins National Monument, in Coolidge, Arizona, just northeast of the city of Casa Grande, preserves a group of Hohokam structures.

The national monument consists of the ruins of multiple structures surrounded by a compound wall constructed by the Hohokam, who farmed the Gila Valley in the early 1200s. "Casa Grande" is Spanish for "big house" (Siwan Wa'a Ki: in O'odham); these names refer to the largest structure on the site, which is what remains of a four story structure that may have been abandoned by the mid-1400s. The structure is made of caliche, and has managed to survive the extreme weather conditions for about seven centuries. Graffiti from 19th-century passers-by is scratched into its walls; though this is now illegal. Casa Grande now has a distinctive modern roof covering built in 1932.


Administrative history

Proclaimed Casa Grande Reservation by an order of President Benjamin Harrison on June 22, 1892 (Note this was long before the National Park Service). It was redesignated a national monument by Woodrow Wilson on August 3, 1918. As with all historical areas administered by the National Park Service, Casa Grande was listed on the National Register of Historic Places on October 15, 1966.

Historic adobes

Between 1937 and 1940 the Civilian Conservation Corps built several adobe buildings to serve as housing and administrative offices for the National Monument. The adobe buildings, constructed using traditional methods, continue in use today and are now listed on the National Register of Historic Places. Because of careful conservation, the physical appearance of Casa Grande Ruins has hardly changed since the 1940s.[1]

Olmsted shelter

In 1932, a ramada was built to shelter the ruins from weathering by Boston architect Frederick Law Olmsted, Jr..[2] In the early twenty-first century, a pair of Great horned owls took up residence in the rafters of the Olmsted shelter.[3]

The Hohokam were a nation that lived in the south-central region of Arizona. Their community was centered around large adobe structures. For unknown reasons, the Hohokam abandoned their structures and left the region around 1450 CE.

The first written records of Casa Grade occurred in 1694. With the advent of train travel, more people began to visit the site between the 1860s and 1880s. During this period, souvenir hunting, graffiti, and vandalism took its toll on the site leading to the creation of the archaeological reserve. In 1892, Casa Grande was the designated as the first archaeological reserve in the United States. It was declared a National Monument in 1918.

To protect the structure from the elements, a wood-and-corrugated-iron shelter was built over it in 1903. In 1932, the Civilian Conservation Corps constructed a more substantial steel shelter over the structure, which is still in use today.


The monument lies within the Sonoran Desert but is surrounded by agricultural fields. Within the boundaries of the monument, natural desert terrain is maintained and is pretty much flat land.
