Though known as Montezuma Castle, it is, in fact, a group of houses built on the side of a cliff. They date back over 600 years.
What is so creepy is that the fifty or so people of the Indian tribe that lived there, one day in around 1425 (we do not know the exact date) simply just upped and left, leaving behind most of their possessions. It was said that even food was left uneaten on the table.
Their disappearance was not discovered for centuries as the spot is so secluded and well hidden. Although it appeared that they left in a hurry, no one knows why they left or where they went.
