There are four majestic Royal Temples carved into the face of the Jabal al-Khubtha. The largest is the Urn Tomb in the center of this photo. The impressive, Complex Classical style includes columns and an urn-shaped ornamentation above the pediment. It was finished in 70 AD as a crypt for Nabataean King Malchus II. The monument was converted into a Byzantine church during the mid-5th century. The two-story arcade beneath it is a vault called the sijin which means prison. To the left is an unidentified tomb with a Step design. On the far left is the Silk Tomb, so named because of the bright, swirling colors on its façade. It was built during the 1st century.
