The Harbaqa Dam was a Roman gravity dam in the Syrian desert between Damascus and Palmyra from the 1st or 2nd century AD.
The remains of the ancient dam are 10 kilometers north of the intersection of the two highways from Damascus via Al-Dumair to Palmyra and from Homs to Baghdad , near Ain al-Baridah.
The core of the dam is made of Roman concrete , which was clad with ashlar on the water and air side. The dam, which is around 21 meters high and around 365 meters long in the area of the wall crown, blocked the Wadi al-Barada. It was originally used to irrigate the surrounding fields, the yields of which supplied Palmyra. In the 8th century, took him to the water supply of 16 kilometers northern of the Caliph Hisham built Qasr al-Hair al-Gharbi ( "Western game reserve Castle"). The water flowed through an open channel (birka) to the bathhouse of the palace and into a large garden ( bustan ) .
