Krak des Chevaliers (French pronunciation: [kʁak de ʃəvaˈlje]) (Arabic: قلعة الحصن), also Crac des Chevaliers, is a Crusader castle in Syria and one of the most important preserved medieval castles in the world. The site was first inhabited in the 11th century by a settlement of Kurds; as a result it was known as Hisn al Akrad, meaning the "Castle of the Kurds"...Since 2006, the castles of Krak des Chevaliers and Qal'at Salah El-Din have been recognised by UNESCO as a World Heritage Site.
