The mysterious cliff dwelling known as Montezuma Castle has overlooked Arizona's Verde Valley for over 900 years. Originally thought to have been built by the ancient Aztecs, later research proved it to be the handiwork of a long-vanished people named the Sinagua. They inhabited the site for over three centuries and then simply walked away to be lost in the mists of time. In this volume, the author traces the history of Montezuma Castle through its construction, abandonment, later discovery, and the diligent efforts of many individuals and organizations to restore and preserve it for future generations. In 1906, Montezuma Castle was designated one of the country's first national monuments by Pres. Theodore Roosevelt. Arizona was still a territory at that time, six years away from becoming the 48th state in the Union.
