Shawbak Castle (Montreal)
The last standing castle

Shawbak Castle is located in a town called Shawbak, It is located less than an hour drive from Petra.
It was built during the age of the crusaders 894 years ago. Shobak castle appears as a natural extension of the hill it is built on.
The castle was strategically important due to the fact that it also dominated the main passage from Egypt to Syria. It successfully resisted a number of sieges until it fell to Saladin's troops in 1189.

Little remains of the original crusader fortifications. It has never been fully excavated and is currently being investigated by an Italian archaeological team from the University of Florence.
You can also go through the secret tunnel leading from the castle itself to a nearby hill.
