Duomo di Milano
Architecture
Begun in 1386 and not structurally complete until the twentieth century, built from pink-veined Candoglia marble floated in on canals. It carries something like 3,400 statues and 135 spires, topped by the gilded Madonnina. The essential move is going up: the rooftop terraces let you walk among the flying buttresses and pinnacles, with the Alps visible on a clear day.
Roof access by stairs or lift, ticketed separately from the cathedral interior. Buy the combined pass and go up late in the afternoon.
