After Roman urban planners, the overall layout of the city has no changed. The Byzantine Empire replaced the Roman Empire, pagan temples were replaced by churches, but the streets remained the same. Muslims did not need a wide Roman-Byzantine-style street and they divided Cardo into several parallel streets, covered them with arched ceilings and an oriental bazaar become from now and forever a new fashion in Jerusalem streets. From the level of the modern street, you can see the pavement of Roman street.
The tour begins in the car park near the Zion gate. This parking lot is the most convenient for wheelchairs and most close to the old city. The route runs along the flat part of the city completely avoiding steps and steep climbs or descents. The path to the Church of the Holy Sepulcher passes through the Jewish and Christian quarters, the ancient Cardo street and the markets of the Christian part of the city.
