Krak des Chevaliers is a Crusader fortress in Syria and one of the most important preserved medieval military castles in the world. It is located 65 km west of the city of Homs, close to the border of Lebanon, and is administratively part of the Homs Governorate.
Krak des Chevaliers was the headquarters of the Knights Hospitaller during the Crusades. It was expanded between 1150 and 1250 and eventually housed a garrison of 2,000. The inner curtain wall is up to 100 feet thick at the base on the south side, with seven guard towers 30 feet in diameter.
