The Karak Castle is a Crusader fortress built in 1142 CE, incorporating stones from older Nabatean, Roman, and Byzantine ruins. It served as the main link in a chain of Crusader fortifications in present-day Jordan. Among its inhabitants was Reynald de Chatillon, renowned for his brutality. He was defeated by Saladin in the Battle of Hattin, and the castle was conquered soon after in 1188 CE. The castle was then refortified in the following two centuries by the Mamluks. It remained in continuous use by various groups, including the Ottomans, into the 19th century. The castle has arrow-slit walls, towers, a dungeon, vaulted halls, courtyards, a school, a mosque, and a large kitchen.
