The fortress was built to protect a vulnerable stretch of the Cairo-Damascus highway (the Via Maris), and was provided with 100 horsemen and 30 foot soldiers. The fortress was also supposed to supply soldiers to protect the hajj route. The fortress is a massive rectangular enclosure with four corner towers and a gate at the centre of the west side. The south-west tower is octagonal, while the three other towers have a square ground plan.
