Climbing the walls by sandysmith
Through a narrow archway on the right hand side of Bootham Bar is a flight of steep steps -climb these to reach the city walls.
Walking the walls amnd ramparts of York you get a great overview of the town, old and modern, and you come come across several of these bars too.
