1. Montezuma Castle National Monument is a prehistoric Native American cliff dwelling located in central Arizona, near the town of Camp Verde. The dwelling was built by the Sinagua people around 700 years ago and consists of twenty rooms built into an alcove high above the ground. The site was named after the Aztec emperor Montezuma by early American settlers, though the Aztecs had no connection to this location. Interesting facts include: - Montezuma Castle is one of the best-preserved examples of a cliff dwelling in North America. - The Sinagua people who lived in Montezuma Castle were skilled farmers, trading with other tribes for exotic goods like shells and copper. - The site was abandoned by the Sinagua people in the 1400s, for reasons that remain unclear. - Montezuma Castle was made a National Monument in 1906 by President Theodore Roosevelt, and today is managed by the National Park Service. 2.
