Montezuma Castle National Monument, AZ - Inhabited over a millennium ago by the Sinagua, these cliff dwellings are nestled in the sheer limestone cliffs overlooking a lush river valley in the otherwise dry and desolate Arizona landscape. When the ruins were discovered by European explorers, it was incorrectly believed to be Aztec in origin. Thus it was named after Montezuma II.
Montezuma Castle was built by the ancient Sinagua Indians over 900 years ago into the cliff alcoves near Camp Verde, AZ and Sedona, Arizona. Montezuma Castle National Monument is open everyday except Christmas Day.
