By contrast, the tall, square tower is 2,000 years old and was built by Herod.
Head to the left to go toward the Christian or Muslim Quarter and the right to reach the Jewish Quarter.

It was announced in August 2014 that the Old City was going to have some work done to make the city more accessable to handicap patrons.

That is the feeling one gets in the Old City of Jerusalem.
