Damascus Gate is one of the main entrances to the Old City of Jerusalem. It is located in the wall on the city’s northwest side and connects to a highway leading out to Nablus, which in the Hebrew Bible was called Shechem or Sichem, and from there, in times past, to the capital of Syria, Damascus; as such, its modern English name is Damascus Gate, and its modern Hebrew name, Sha’ar Shkhem , meaning Shechem Gate, or Nablus Gate. Of its Arabic names, Bab al-Nasr means "gate of victory," and Bab al-Amud means "gate of the column." The latter name, in use continuously since at least as early as the 10th century, preserves the memory of a Roman column towering over the square behind the gate and dating to the 2nd century AD.
