A National Historic Landmark, Pueblo Grande was the site of a major community of the Native American Hohokam culture. The settlement thrived for about a thousand years, beginning around 450 A.D. Located in the heart of present-day Phoenix, the park includes a first-class museum and preserves the remains of a major Hohokam platform mound and a ballcourt. There are also re-creations of ancient Hohokam houses. You can learn more by visiting the park’s website or Wikipedia.

The steep side of the platform mound is visible in this view. It has suffered considerable erosion over the years but at its prime, the mound was nearly 25 feet tall and the size of a football field.
