Habis and High Place Castles
قلعة الحبيس و قلعة المذبح
In addition to the Wadi Musa Castle just outside Petra, two more Crusader castles were built inside Petra to serve as watchtowers and signaling posts on the sight line with Jerusalem. The two castles currently lie in ruins from past earthquakes.
Within the ancient city of Petra. The Habis Castle is atop the Habis Mountain (where the Unfinished Tomb is located). The High Place Castle is atop the Madbah Mountain (where the Treasury building is located).
