The Hippicus Tower was named after Herod the Great's general and friend. It stood 132 feet high. It was one of the three towers built to protect Jerusalem on the northwest side. It was located near Herod's Palace to the north and in the middle of Jerusalem's northern wall, to the west of the western wall of the Temple Mount. It is undoubtedly located on the exact same site as Nehemiah's Tower of Hananeel, according to Josephus.
