This building, known as The Treasury is one of a series of buildings built by the Nabateans who followed a pagan religion and were closely linked to the people of Thamud. They were renowned for their elaborate skill of carving into rocks.
- The Nabateans were a Semitic people, Arabs of southern Jordan, Canaan and the northern part of Arabia,
- Petra lies on the slope of Mount Hor and close to the town of Wadi Musa (the valley of Moses). Harun (upon him be peace), the brother of Musa (upon him be peace) is buried close by, as is Miriam, their sister.
- The Nabateans worshipped the Arab gods and goddesses of the pre-Islamic times as well as few of their deified kings. Many statues carved in the rock depict these gods and goddesses. Three of the idols worshipped by the disbelievers at the time of the Prophet (peace and blessings of Allah be on him), Lat, Uzza and Manat have their origins with the Nabateans. They used to believe that they were the daughters of Allah.
One of the first things that can be seen around the entrance to Petra are three huge blocks, standing 6 to 8 metres high. Tradition holds that they contained ‘jinn’, placed there to guard the city.
