Florence.

Florence manages to pack several centuries of world-altering art and architecture into a remarkably walkable historic center. Rather than feeling like a static museum, the cradle of the Renaissance thrives as a living city where medieval civic buildings like the Palazzo Vecchio still function as city halls. Days here easily layer heavy-hitting culture—from Brunelleschi’s red-tiled dome and the Uffizi’s Botticellis to Michelangelo’s David—with effortless, modern street life. You can spend the morning tracing the legacy of the Medici family at the Boboli Gardens, the afternoon hunting down leather workshops and historic perfume-makers, and the evening sipping Tuscan wine from a Renaissance-era wine window before catching the sunset over the Arno from Piazzale Michelangelo.
