JERUSALEM, ISRAEL—The Guardian reports that Rina Avner and Kfir Arbib of the Israel Antiquities Authority have found evidence of a 2,000-year-old watchtower and a wall that protected a “new” area of Jerusalem that had developed outside of the city’s two existing defensive walls. The Jewish historian Josephus described Titus’s breach of such a third wall in A.D. 70, when Roman legions invaded, sacked the city, and destroyed the Second Temple. Large stones that the Romans may have fired from catapults at the sentries in the tower have also been uncovered. It is thought that Roman forces used battering rams on the wall while the catapults provided cover. To read about another discovery in Jerusalem, go to “Rubaiyat Pot.”
