Day 1 — Piazza del Campo and the city’s “shell”
🚶 Start from the heart of Siena — Piazza del Campo. The shell-shaped square gently slopes down toward the Palazzo Pubblico with the Torre del Mangia: brick, Gothic lines, and semicircles of paving stones pull the city together. Walk along the edges of the square’s “petals,” sit by the Fonte Gaia, then slip into the alleys toward the Loggia della Mercanzia and the narrow streets of Banchi di Sotto: here you can hear the city speaking in a half-whisper — through shutters, bells, and footsteps on stone.
