On a budget, weigh it — Giotto's Campanile isn't cheap for what it is.
Included in Brunelleschi Pass €30
The case for the tower over the dome is one specific thing: from up here Brunelleschi's dome is in your photograph, the great russet shell filling the frame, whereas the dome climb leaves you standing on the one thing you came to see. The banded white-green-pink marble is also gorgeous at eye level on the way up. The honest catch is the same 414 stairs and no lift, and the landings jam with two-way traffic — but if you're choosing one climb and want the iconic shot, this is the smarter one.
