A castle on the left bank of Lake Assad in Raqqa Governorate, Syria. Its site, formerly a prominent hill-top overlooking the Euphrates Valley, is now an island in Lake Assad that can only be reached by an artificial causeway. Although the hilltop on which the castle sits was possibly already fortified in the 7th century, the current structures are primarily the work of Nur ad-Din Zangi, who rebuilt the castle from 1168 onwards. Since 1965, several excavations have been carried out in and around the castle, as well as restoration works of the walls and towers. The castle was a Turkish exclave between 1921 and 1973.In 1973, in response to the rising water level of the newly created Lake Assad, the reputed tomb of Suleyman Shah and the associated exclave were moved to a new location north of Qal'at Ja'bar and the castle itself became Syrian territory.
Was only subject to a brief occupation by Crusaders in 1102. In 1146, Zengi besieged the castle, but he was murdered there by one of his own slaves. In 1168, Qal'at Ja'bar passed into the hands of Zengi's son Nur ad-Din, who undertook major construction works at the castle. Most of what can be seen today dates to this period. The castle was heavily damaged during the Mongol invasions of Syria.
Qal'at Ja'bar measures 370 by 170 metres (1,210 ft × 560 ft). The castle consists of a stone-built wall with 35 bastions around a rock core, and is partially surrounded by a dry moat. The layout of the castle is very reminiscent of the much better preserved citadel of Aleppo. The upper parts of the castle are built from baked bricks. The entrance to the inner parts of the castle consists of a gatehouse and a winding ramp cut out of the rock. Inside the castle are the remains of a vaulted hall, as well as minaret that was probably built by Nur ad-Din, and that is the highest part of the castle. The brickwork that is currently visible is mainly the result of extensive restoration works by the Syrian Directorate-General of Antiquities and Museums.
