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.

Flora and fauna

Mammals such as the javelina, coyote, Mexican Wolf, bighorn sheep, and bobcat live in this area of the desert. Other animals like the bat, fox, skunk, cottontail, and jackrabbit also make this their home.
