Touring the UK, this stop came to York. York's ancient wall is the most complete and longest of the entire ancient wall in England, the wall was first built during the Roman reign as a barrier against foreign enemies, and was then re-strengthened by the Danish occupiers. The city wall is centered on the York Cathedral, and it takes about 2 hours to circle the city wall. There is no charge for visiting the York City wall. Anyway, it is the appearance of standing in front of it. I saw a section and there was only one wall left.
