Do not take a backpack straight to the Dome, Bell Tower, Baptistery, or Santa Reparata entrance. The Opera di Santa Maria del Fiore requires backpacks of every size to be deposited first at its Large Cloakroom at Piazza Duomo 38/r. Handbags and other containers larger than 35 × 30 × 15 cm must also be checked. The service is included with qualifying Duomo passes, but it is not a general left-luggage facility for sightseeing around Florence.
The Florence Duomo bag rules are stricter than the phrase “large bags prohibited” suggests. A tiny backpack still counts as a backpack and must be left behind. A small handbag or crossbody bag within the permitted dimensions can normally go inside, subject to the final decision of security staff.
The rule that catches backpack users out
The current official cloakroom regulations make an important distinction between backpacks and other bags.
- Backpacks: every backpack, regardless of its dimensions, must be deposited. The rule also covers bags specifically designed to be worn on the back.
- Handbags and other bags: these must be deposited if they exceed 35 × 30 × 15 cm.
- Suitcases, parcels and containers: larger items must also be deposited, provided the cloakroom is permitted to accept them.
- Anything considered unsafe: security staff can refuse an item even if it technically fits within the size limit.
So changing from a 30-liter travel pack to a miniature daypack does not solve the problem. Changing to a genuinely small crossbody or handbag may.
Where the Duomo luggage storage actually is
For the Dome, Giotto’s Bell Tower, Baptistery and Santa Reparata, use the Large Cloakroom at Piazza Duomo 38/r. It is beside the entrance to the Opera del Duomo Museum.
The “38/r” matters. Florence uses red numbers for many commercial premises, and the r means rosso, or red. Do not simply look for an ordinary building number 38 and assume you are in the wrong place. Look for the luggage-storage entrance near the museum and the Italian wording Deposito Bagagli.
This is separate from the museum’s own smaller cloakroom at Piazza Duomo 9.
What happens when you deposit your backpack
The process is more formal than handing a bag across a counter. For the Large Cloakroom, access is tied to your admission ticket.
- Go to Piazza Duomo 38/r before approaching your monument entrance. Do this before the start of any timed visit that requires you to be bag-free.
- Have your ticket ready. The Large Cloakroom can be accessed by scanning the barcode on the ticket for the monumental complex.
- Your bag must be properly closed. The regulations also require the depositor to report its contents when checking it in.
- Staff tag the bag and give you a corresponding receipt or numbered tag.
- Keep that receipt carefully. Bags are normally returned to whoever presents the matching receipt. Staff are not simply checking the collector’s name against the original depositor.
- Collect the bag after your visit. The cloakroom is intended to support the monument visit, not to store your luggage for the rest of the day.
The Large Cloakroom is currently listed as open daily from 7:30 am to 8:15 pm, except Christmas Day, New Year’s Day and Easter Sunday. Hours can change, so check the official Duomo ticket FAQ before relying on the service, especially for an unusually early or late visit.
Do not put your passport, wallet or valuables in the checked bag
The cloakroom does not accept money, jewelry, precious metals, documents or other valuables as deposited contents. That matters particularly for the Dome because Brunelleschi Pass holders must show identification together with their nominative ticket at the entrance.
Keep your ID, phone, wallet and other important items on your person or in a small permitted bag. Do not bury your passport in the backpack and hand the whole thing over.
Bags weighing more than 25 kg are also not accepted. The Duomo cloakroom is therefore not a substitute for checking several days’ worth of exceptionally heavy travel luggage.
The free Cathedral has a different problem
Entry to Santa Maria del Fiore itself is free, but the official Cathedral information says bulky luggage and bags are not allowed inside.
The complication is that the Large Cloakroom’s access procedure is based on scanning an admission ticket to the monumental complex. The Cathedral does not issue an ordinary sightseeing ticket because entry to the nave is free.
If your only plan is to enter the free Cathedral and you are carrying a suitcase or bulky travel bag, do not assume Piazza Duomo 38/r will function as free public luggage storage. Leave the luggage at your accommodation or a dedicated commercial storage service before joining the Cathedral line.
Museum-only visitors use a different cloakroom
The Opera del Duomo Museum has a Small Cloakroom at Piazza Duomo 9. Museum-only visitors who need to check a backpack use this facility rather than the Large Cloakroom.
The same backpack rule is surprisingly strict here: backpacks of any size or bags designed to be worn on the back must be deposited. However, the official regulations specifically say that suitcases cannot be accepted in the Small Cloakroom for security reasons.
If you arrive in Florence with a rolling suitcase and intend to visit only the museum, arrange proper luggage storage elsewhere rather than discovering this at the museum door.
Timed tickets make the bag rule more important
Bag trouble is most costly when you have a timed admission. The Dome, certain Bell Tower tickets and Santa Reparata reservations use fixed slots. The Opera currently guarantees only about five minutes of lateness beyond the scheduled entry time, and issued reservations cannot simply be moved to a later slot.
That means the wrong sequence is:
monument queue → security sees backpack → walk to cloakroom → deposit bag → hurry back.
The safer sequence is:
cloakroom first → deposit anything prohibited → walk to the correct monument entrance → present yourself for the booked slot.
The Opera asks timed visitors not to gather at the actual monument entrance far in advance, so you do not need to stand in the Dome queue excessively early. You do need to finish the separate bag-storage job before your admission time becomes critical.

What to carry instead of a daypack
For a Duomo-heavy sightseeing day, the simplest setup is a small crossbody or handbag that stays comfortably below 35 × 30 × 15 cm. Remember that dimensions do not override security judgment, so compact is better than trying to arrive with a stuffed bag measuring exactly at the limit.
Families should pay particular attention to this. A child’s tiny backpack is still a backpack. If it contains medication, documents, wipes, snacks or other things you expect to need immediately, reorganize those essentials before checking the bag rather than discovering after the handover that something important is inside.
Tripods and potentially dangerous metal objects are also restricted. Security checks take place at the monuments, so passing the size test does not automatically mean every object inside your small bag can enter.
If the Duomo is one timed stop among several museums and sights, it helps to plan your Italy route so you are not repeatedly collecting luggage, crossing the center and returning to the square between reservations.
If security turns you away because of your bag
If you still have time before a booked entry, follow the staff’s direction and go immediately to Piazza Duomo 38/r. Do not argue that your backpack is “small enough.” Under the published regulation, backpack size is irrelevant.
If the issue is a small handbag that security considers unsafe or oversized, their decision controls entry even if your own measurements suggested it would qualify.
If you are already outside the permitted lateness window for a timed monument, depositing the bag does not guarantee that staff will admit you when you return. Reservations are fixed, so treating the cloakroom as an errand to complete after reaching security is a risky plan.
If you lose the cloakroom receipt or forget your luggage
Guard the luggage receipt like a ticket. If it is lost, staff can hold the item while you establish ownership, potentially by showing your monument ticket and accurately describing the bag. Retrieval is therefore much quicker when you still have the numbered receipt.
Baggage must be collected by the cloakroom’s closing time. If you leave something behind, the regulations direct luggage enquiries and requests for forgotten items to luggage@duomo.firenze.it. Where return shipping is required, the depositor must arrange collection by courier at their own expense.
The easiest way to avoid all of this is simple: for a Dome or Bell Tower day, leave the backpack at your hotel if you can. If you need it while moving around Florence, take it to Piazza Duomo 38/r before the timed part of your visit, keep your ID and valuables with you, and hold on to the cloakroom receipt until the bag is back in your hands.
