The base of the wall to the north consists of 13 courses of large Herodian stones. These are the remains of a tower,either the Hippicus of Phasael Tower, which was built by Herod to defend his palace. The upper courses of the tower are Mameluke. At the foot, we can see the remains of a wall from the Byzantine period. The end of the new wooden walkway, which leads to the exhibition halls in the northwest tower, connects to the plaza.
Steps descend from the plaza to the moat.
We continue up and cross to the stone entry bridge, which is supported by two arches resting on a column set in the moat. On the outside of the guardrail of the bridge is a circular inscription, mentioning once again Suleiman the Magnificent. Above the main entrance is an empty niche, which once held a Mameluke inscription, commemorating the restoration of the entrance in the year 1312. The entrance was originally built in the Crusader period. The entrance area opens into the guardroom, which has stone benches along the walls.
