Chester is one of the few cities in Britain where the old medieval walls still survive largely intact (though I recommend Conwy in North Wales as another town where they still stand and arguably are more spectacular). Anyway, I was in Chester last week and got the chance to walk along a part of the wall, from Newgate (see picture below) to the River Dee. I shot this video at the same time.
Access to the wall is free.
A few photos to illustrate the stretch I was on:
