Florence concentrates a high number of landmark sites within a small radius. The Duomo complex, Uffizi Gallery, and Accademia form the core trio for most first time visitors. These three alone require advance booking and structured time slots. Add Piazza della Signoria, Ponte Vecchio, and a walk through Oltrarno, and you already have two full days.
Beyond that, popular additions include Pitti Palace and Boboli Gardens, Santa Croce, Santa Maria Novella, and Piazzale Michelangelo for sunset views. Each adds context, but they should be layered carefully to avoid museum fatigue. Florence is compact, but mentally dense.
The key is sequencing. Fix timed entries first, group nearby sites on the same day, and avoid crossing the Arno repeatedly without reason.
