Montezuma Castle National Monument, Arizona

Just got back from a lovely trip to Arizona. Photo highlights were the visit to Montezuma Castle National Monument. To quote from the website (http://www.nps.gov/moca/):
"It's not a castle and Montezuma was never here.
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."
