Qasr al-Hayr al-Sharqi, Syrian desert - Fotografía de stock

Qasr al-Hayr al-Sharqi (Eastern al-Hayr Palace or the "Eastern Castle") is a castle (qasr) in the middle of the Syrian Desert. It was built by the Umayyad caliph Hisham ibn Abd al-Malik in 728-29 CE in an area rich in desert fauna. It was apparently used as a military and hunting outpost. The palace is the counterpart of Qasr al-Hayr al-Gharbi, a nearby castle palace built one year earlier. Qasr al-Hayr al-Sharq is 27 kilometres (17 mi) from Al-Sukhnah and 100 kilometres (62 mi) from Sergiopolis (Rusafa), near Bishri Mountain near Palmyran Middle Mountains.
