Some of the stones with which the castle was built have crosses carved into them, giving credence to a tradition, recounted by a 13th century Arab historian that: “an ancient monastery once stood on the site, inhabited by a Christian named Ajloun; when the monastery fell into ruin, the castle took its place and the name of the monk".

The castle today is beautifully preserved and is a popular attraction for foreigners and Jordanians alike. The structures, towers, chambers, galleries and staircases that form part of the town as well as the beautiful scenery that surrounds the hills nearby will captivate you.
