City street

This gate divided the administrative and religious section of Pompeii from the commercial/residential zone. Those round blocks in the middle were stepping stones placed there so that the citizens didn't have to walk through the garbage and running water laying in the street. They were spaced far enough apart so that a chariot's wheels could pass through. An interesting fact I learned on this tour was that the width of a Roman chariot's wheels is what we still use as the gauge on our railroads today.
