The Montreal Castle was built by the Crusaders on top of this rocky plateau in 1115 AD. To appreciate its enormous size, notice the pathway leading up to this citadel. This desolate Mont Rial hilltop provided an excellent means of defense against invaders. Krak de Montreal is located near Shoubak, a small town of Muslims. This ancient fortress is one of several popular archeological sites in Ma’an Governorate. Others include nearby Little Petra and the world famous Petra, the number one tourist attraction in Jordan.
