Duomo Florence reservation: dome slots and rules

Duomo Florence reservation: the slot that does not move

You enter the dome at the printed hour. Five minutes late and Opera can refuse you, with no refund. Grey “0”s on the calendar are real sell-outs: the ticket office does not hide extra places.

Quick summary
Price from	€30 pass / €58 partner
What you book	Dome or tower or crypt
Flexibility	None
Time	Arrive ±5 min

The query reservation Duomo Florence is small in volume and huge in damage: a mistake costs €30 and the morning. Validity is 3 days from the slot date; the vertical slot always sits on day one.

Ticket comparison

Official: pick pass + hour on tickets.duomo.firenze.it. Partner: the widget on this page, different prices, same dome clock.

Timing is everything

In spring, book 2–3 weeks ahead. Mid-August: think a month. November (outside closures) 48 hours can still work.

The insider entry

Mandorla with a dome slot. Tower: tower base. Ghiberti crypt: crypt time, not the façade.

How to save

Do not buy “flexible” from third parties: Opera does not sell it. One correct date beats three wrong dates “refunded” in chat.

How to get there

Budget 15 minutes from the station to the slot, not 8.

Official hours and pass prices: Opera di Santa Maria del Fiore, tickets.duomo.firenze.it. Partner (Tiqets) prices as of August 2026; they change.
