Usage of the Citadel hill dates back at least to the middle of the 3rd millennium BC. Subsequently occupied by many civilizations including the Greeks, Byzantines, Ayyubids and Mamluks, the majority of the construction as it stands today is thought to originate from the Ayyubid period. A great deal of conservation work has taken place in the 2000s by the Aga Khan Trust for Culture in collaboration with the Syrian Directorate General of Antiquities.
The Citadel in its present form today, is situated on a mound which has an elliptical base with a length of 450m and width of 325m. At the top this ellipse measures 285m by 160m with the height of this slanting foundation measuring 50m. In the past, the entire mound was covered with large blocks of gleaming limestone, some of which still remain today. The mound is surrounded by a 22m-deep and 30m-wide moat, dating from the 12th century[25]. Notable is the fortified gateway, accessible though an arched bridge. This feature was an addition from the Mamluk government in the 16th century. A succession of five right-angle turns and three large gates (with carved figures) leads to the main inner castle entrance.
Particularly interesting in the interior are the Weapons' Hall, the Byzantine Hall and the Throne Hall, with a restored decorated ceiling.
Today, the citadel is an important tourist attraction and a site of archaeological digs and studies. The amphitheater is often used for musical concerts or cultural events.
