The leaning tower of Pisa was one of those "must see" attractions that I had always wanted to visit. If it was in England there is no way health and safety would let you climb those treacherously slippery, worn marble steps. But climb it we did, and it was so worth it. You can really feel the lean as you climb up in a spiral and find that sometimes despite going up, it definitely feels like you are going in a downward direction. It really is a feat of engineering, and good on them for keeping it standing for such a long time!
