Each monument in the Duomo complex operates on its own schedule, and these can change seasonally or for religious services. The Cathedral is open Monday to Saturday, typically from mid-morning until mid-afternoon, and remains closed to tourists on Sundays. The Dome, Bell Tower, Baptistery, and Museum all open earlier and close later, offering more flexibility for sightseeing. Planning your route around these times helps you make the most of your ticket's three-day validity and avoid last-minute disappointments.
