5. City Walls
Since the times when Rome governed the area of York, the city has been defended by outer walls. York has the most intact mileage of city wall than any other city in all of England and are easily accessed by the public to allow for views of the city. The walls are separated by bars, or guardhouses, and often go by the name The Bars. The walkway along the wall contains markers that point pedestrians to notable areas or buildings from history.
