Petra (Greek "πέτρα" (petra), meaning rock; Arabic: البتراء, Al-Batrāʾ) is a historic and archaeological city in the Jordanian governorate of Ma'an that has rock cut architecture and a water conduits system. Established sometime around the 6th century BC as the capital city of the Nabataeans, it is a symbol of Jordan as well as its most visited tourism attraction.
Al Khazneh ("The Treasury"; Arabic: الخزنة) is one of the most elaborate buildings in the ancient Jordanian city of Petra. As with most of the other buildings in this ancient town, this structure was carved out of a sandstone rock face. It has classical Greek-influenced architecture, and it is a popular tourist attraction.
