Al-Khazneh is a magnificent example of 1st century Nabataean architecture and the most photographed façade in Jordan. The 141 foot tall Treasury was carved into a massive cliff along the valley of Wadi Musa. Some believe this Valley of Moses is near where the prophet miraculously drew water from a rock during the Exodus. The Treasury is also where Harrison Ford sought the Holy Grail during the climax of “Indiana Jones and the Last Crusade.”
