I have often walked along or on the walls, on the inner city side or the outer one. Over many visits I have seen them and their surroundings change. They have been restored, and the area around them has been cleared, turned into parks or otherwise “landscaped”. I have taken so many pictures and to so many directions that I cannot identify each spot. Some routes I took are clear, I try to show them consecutively. Others are too complicated. One reason is that I liked some particular towers that I used as centres to organise pictures of themselves, and some sights nearby. Many recent pictures have GPS and can be located using the “view map” option.
