Visit York City Walls to explore one of the most complete medieval town defence systems in England. You'll find that the wonderfully intact walls run for two-and-a-half miles around the ancient heart of the historic city and include five fortified gateways where visitors would have to pay a toll in ancient times. A few sections even include stonework dating back to the original Roman city walls of York. It's easy to walk along all of the wall or to tackle small sections, but whatever you do, you'll be able to enjoy amazing views across the city rooftops towards the Minster.
