“Al Khazneh (“The Treasury”‎‎) is one of the most elaborate temples in the ancient Arab Nabatean Kingdom city of Petra. This structure was carved out of a sandstone rock face. The treasury was built by the Arab Nabateans, coinciding with the time of the Hellenistic and Roman Empires and so has classical Greek-influenced architecture.” More on Wikipedia.
