The World's Most Famous Treasury Is Actually A Graveyard Petra's Treasury, contrary to popular belief, is not a looming maze of booby-trapped rooms designed to separate the righteous from the unworthy, but rather a relatively small area that is most likely a beautifully decorated graveyard. Any buried treasure was most likely removed a long time ago, but the Treasury facade is a work of art, lovingly carved by the Nabataeans centuries ago.
