The ancient museum is located inside the natural rock, within one of the Nabatean caves, leading to Al Habees Castle in Petra, and was established in 1963. It consists of a main hall and two side rooms. Visitors climb up to the museum.
Upon an agreement signed between the Jordanian authorities and a Japanese on 1 March 2014, a new modern site of Petra museum was built. It took five years and more than seven million dollars to build the new 1800 m2 site.
