The Treasury, also known as Al-Khazneh, is a stunning rock-cut tomb in Petra, Jordan. Carved out of sandstone around the 1st century AD, it features intricate sculptures and mythological figures associated with the afterlife. The facade is elaborate, but the interior is more plain, with a main chamber and three antechambers. This iconic site has gained fame through its appearance in Hollywood films like Indiana Jones and the Last Crusade, making it a must-visit for tourists exploring the ancient city of Petra.
