A short journey west of Jerash, through pine forests and olive groves, brings you to the town of Ajloun. Here is Qala'at Al-Rabad, the castle of Ajloun, which was built in A.D. 1184 by Azz Al Din Usama, whose cousin, Salah Al Din, defeated the Crusaders in A.D. 1189.
A fine example of Islamic architecture, the fortress dominated a wide stretch of the northern Jordan Valley and passages to it. From its hill-top position, Castle of Ajloun protected the communication routs between south Jordan and Syria, and was one of a chain of forts which lit beacons at night to pass signals from the Euphrates to Cairo.
Today, Ajloun castle is a splendid sight and a fascinating warren of towers, chambers, galleries and staircases to explore, while its hill -top position offers stupendous views of the Jordan Valley.
