I've seen the Sistine Chapel and it's OK but that's not what art is about. I've lived in New York City and appreciated the Metropolitan, The Guggenheim, Peter Cooper, The Jewish Museum, The Brooklyn Museum, The Modern, The Whitney, and, of course, the many galleries. Here in Helsinki I regularly visit The Atheneum, Kiasma, Amos Anderson, and quite a few others. There is a lot of wonderful stuff in all of them and quite a bit of crap, but it's always fun to look and learn and try out new things for myself.
