Byblos Castle is a Crusader castle in Byblos, Lebanon. In Crusader times it was known as the castle of Gibelet or Giblet.
The castle was built by the Crusaders in the 12th century from indigenous limestone and the remains of Roman structures.
The finished structure was surrounded by a moat.
It belonged to the Genoese Embriaco family, whose members were the Lords of Gibelet.
Saladin captured the town and castle in 1188 and partially dismantled the walls in 1190.
Later, the Crusaders recaptured Byblos and rebuilt the fortifications of the castle in 1197.
In 1369, the castle had to fend off an attack from Cypriot vessels from Famagusta.
The Byblos Castle has distinguished historical buildings for neighbors.
Nearby stand a few Egyptian temples, the Phoenician royal necropolis and the Roman amphitheatre.
