One day
Start early at the Duomo for the dome climb, then Giotto's Campanile and the Baptistery around the same square, before the crowds thicken. Walk south into Piazza della Signoria for the free sculpture under the Loggia dei Lanzi and Palazzo Vecchio, then straight into the Uffizi on a pre-booked slot. Come out at the river, cross Ponte Vecchio into the Oltrarno, and climb through San Niccolò to Piazzale Michelangelo for the city laid out under the dome as the light drops.
