The security of the Crusader Kingdom of Jerusalem in the twelfth century was dependent upon a network of fortifications, mainly along its eastern border which was vulnerable to Muslim attacks.
The Hospitaller castle of Belvoir was one of these. It is the first datable true concentric castle. It was built shortly after 1168 on top of a basalt plateau. Twelfth century Muslim historians refer to it as a ‘nest of eagles' and the 'dwelling place of the moon’. About 50 knights and 450 soldiers lived in Belvoir, along with their families and staff.
Though in ruins it is one of the best preserved crusader castles in Israel - and not to be confused with the castle in England also called Belvoir Castle.
