Hiking in Umbria - Abbeys and Art in the Apennines
Brunelleschi's Duomo is a feat of architecture, sure, but it also makes an ideal observation deck. If you can make your way up the 463 steps (no elevator, and some passages that would make the claustrophobic run screaming), you'll be rewarded with pristine, 365-degree views of the city and all of Tuscany stretched beyond. For a view of the Duomo, climb Giotto's Bell Tower next door instead.
Botticelli's The Birth of Venus may symbolize true beauty inside the Uffizi, but the museum is exquisite on the outside as well, with its symmetrical columns and stately windows. We like to stroll the perimeter once the museum has closed, when Florentine couples and families come out to do the same.
