The Treasury grows
The 1.2 kilometer Siq leads you to the most familiar and best preserved site in Petra, the huge facade known as the Treasury. In fact, nobody knows what the purpose of this structure was, but it was probably used for tombs as well as other purposes. Like most of the tombs, dwellings and other structures in Petra, the Treasury was built by cutting away the sandstone in the cliffs, not by erecting components. The Treasury shows Nabatean, Greek and other contemporary influences.
