In the year 70, a Roman force led by Titus put down a rebellion by the Jews in Palestine and destroyed the city of Jerusalem.
Titus became Roman emperor nine years later, but he reigned for only two years. The next emperor, Domitian, erected an arch in Rome to celebrate Titus’s victory in Palestine.
That arch still stands in Rome, near the colosseum. The Arch of Titus is one site in Rome that Jewish visitors steer clear of. Because of Titus’s destruction of Jerusalem, Jewish authorities centuries ago declared that any Jew who waked under the arch would no longer be a Jew.
To this day, no Jew has ever knowingly walked under the arch!
