In addition, the casemate entrances in the city wall also indicate that the gates should be dated to the Iron Age. In the casemates located to the right of each gate, the entrances are located in the right-hand corner of the casemates. In the casemates located to the left of each gate, the entrances are located in the left-hand corner of the casemates. Such a pattern could have been created only when the gates and the city wall were built as one unit.
