The Walls of Jerusalem surround the Old City of Jerusalem. In 1535, when Jerusalem was part of the Ottoman Empire, Sultan Suleiman the Magnificent ordered the ruined city walls to be rebuilt. The work took some four years, between 1537 and 1541. The walls are visible on most old maps of Jerusalem over the last 1,500 years.
