Jewish Quarter Excavations/Hillel Geva and Avital Zitronblat

The tower excavated by Avigad originally stood 30 feet high. Its 12-foot-thick walls are constructed of unworked boulders reinforced at the corner by rectangular ashlars—the same construction used in the offset discovered by Reich and Shukron. Babylonian arrowheads recovered from the base of Avigad’s tower suggest that it was a focal point in Nebuchadnezzar’s assault on Jerusalem in 586 B.C.
