وادي موسى
Two further Crusader-period castles are known in and around Petra: the first is al-Wu'ayra, situated just north of Wadi Musa. It can be viewed from the road to Little Petra. It is the castle of Valle Moise which was seized by a band of Turks with the help of local Muslims and only recovered by the Crusaders after they began to destroy the olive trees of Wadi Musa. The potential loss of livelihood led the locals to negotiate surrender. The second is on the summit of el-Habis, in the heart of Petra, and can be accessed from the West side of the Qasr al-Bint.
