I don’t have much to say about Milan, as Derek and I were on there for a day. I can tell you that on the whole it was not as “glamorous” as I was expecting. And, if there’s one “must see” for Milan it is without a doubt the view from the top of the cathedral.
The climb up to the roof snakes out and around the hundreds of flying buttresses, columns, statues, gargoyles, and every other type of gothic architectural decoration known to man. Never have I seen so much intricate marble-work on a church at such an amazingly close distance. You can literally reach out and touch it all. And, your reward upon reaching the summit is not just the spectacular view of the city, but the uneasy yet awe-inspiring feeling of standing on the actual slanted marble roof of the nave, which vibrates below your feet with from bellow of the grand pipe organ inside the cathedral. True, there are plenty of churches that let you climb up their bell towers or domes, but Milan’s is the only one I’ve ever been to that lets you run around the entire roof. It’s a tremendous experience.
