Stunning architecture poster of Al Khazneh in the historical and archaeological city Petra (Raqmu), Jordan. Al Khazneh, also known as The Treasury, is a temple made out of sandstone and is believed to be a mausoleum of the Nabatean King Aretas IV in the 1st century AD. The name Treasury derives from the legend that bandits and pirates hid their loot in a stone urn within the temple and many people therefore believed it was filled with treasure. The dimensions of the poster include a built-in picture mount.
