St Mary's Wall around the city of York

I walked the whole length of the walls, around the city. No idea how long it was, but I know my feet were aching lol.

The English city of York has, since Roman times, been defended by walls of one form or another. To this day, substantial portions of the walls remain, and York has more miles of intact wall than any other city in England. They are known variously as York City Walls, the Bar Walls and the Roman walls (though this last is a misnomer as very little of the extant stonework is of Roman origin, and the course of the wall has been substantially altered since Roman times).
