One of the most original monuments in Jordan, and perhaps in the Hellenistic period in the Near East, is the village of Iraq al-Amir in the valley of Wadi as-Sir, southwest of Amman, which is home to Qasr al-Abd ('Castle of the Slave'). Other nearby ruins include a village, an isolated house and a fountain, all of which are barely visible today due to the damage brought by a major earthquake that hit the region in the year 362. Qasr al-Abd is believed to have been built by Hyrcanus of Jerusalem, who was the head of the powerful Tobiad family. Shortly after he began the construction of that large building, in c. 170-168 BC, upon returning from a military campaign in Egypt, Antiochus IV conquered Jerusalem, ransacked the Temple where the treasure of Hyrcanus was kept, and appeared determined to attack Hyrcanus. Upon hearing this, Hyrcanus committed suicide, leaving his palace in Philadelphia uncompleted.
