Montezuma Castle National Monument …

was designated on this date in 1906. The National Park Service says:

Nestled into a limestone recess high above the flood plain of Beaver Creek in the Verde Valley stands one of the best preserved cliff dwellings in North America. The five-story, 20-room cliff dwelling served as a “high-rise apartment building” for prehistoric Sinagua Indians over 600 years ago. Early settlers to the area assumed that the imposing structure was associated with the Aztec emperor Montezuma, but the castle was abandoned almost a century before Montezuma was born.
