The Barbican of Jerusalem was a fortification in the Rich District of Jerusalem, located just next to the Bab Ariha and Saint Anne's Church. The barbican was surrounded by walls and consisted of one guarded entrance gate and one exit.
Inside of the walls was a building which contained the slave warehouse of the Templar slave trader Talal. In 1191, the Assassin Altaïr Ibn-La'Ahad infiltrated the barbican in order to assassinate Talal in his warehouse.
- Although the form of the Barbican of Jerusalem corresponds to a typical barbican, the expression does not apply, since barbicans are usually located on the outer side of a city's walls.
