The Temple Mount Wall

The wall surrounded the Temple Mount on four sides. Its height was about forty cubits, except for the eastern wall, which was shorter. The wall delineated the area of the holy Temple Mount. The wall had five gates: the Kiponos Gate in the west, the Shushan Gatein the east, the Tadi Gate in the north and the two Chulda Gates in the south. At the corners of the walls were watchtowers in which the Levites kept watch. The eastern side of the wall was the oldest, dating from the time of Solomon's Temple. It is generally thought that the other walls were built by Herod.
