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.

This view shows a set of excavated rooms on top of the platform mound. More than 50 platform mounds have been discovered across Arizona, with this being one of the largest. They appear to have been placed at regular intervals along the route of their ancient irrigation canals.
