The most famous of the desert castles is Qasr Amra. This was built by the Umayyads as a pleasure and sporting retreat and contains an early 8th century baths complex in a triple-vaulted building full of colourfully painted frescoes. Although somewhat scarred by time, these frescoes depict dancing women and the then-abundant animal life of the desert area. The original well and underground water system can still be seen here.
