Atop the city walls is the rampart allowing you to walk entirely around the perimeter of old Jerusalem. We choose to go one-fourth of the way around, getting off at the next gate.
Walk about Zion, go around her, count her towers, consider well her ramparts, view her citadels, that you may tell of them to the next generation. For this God is our God for ever and ever; he will be our guide even to the end. (Psalm 48:12-14)
