Porta del Cielo or OPA SI pass: which Siena Cathedral ticket is right for you?

What does each Siena Cathedral ticket include?

The OPA SI pass is the ticket for the Cathedral complex. It covers the Cathedral itself and the Piccolomini Library inside it, with Pinturicchio's frescoes of the life of Pope Pius II. It covers the Museo dell'Opera, and with it the panorama from the unfinished façade of the New Cathedral. It also covers the Crypt and the Baptistery. That is five places on one ticket, all on or beside Piazza del Duomo.

The Gate of Heaven ticket contains all of the OPA SI pass and adds one thing. That is an escorted walk through the roof spaces of the Cathedral. These attic rooms had never been open to the general public until the walk began in 2013. The operator describes it as walking above the star-painted vaults, with views both into the Cathedral and out over the city. The name comes from Jacob's dream in Genesis, where he calls the place the gate of heaven.

So the choice is simpler than it first looks. You are not picking between two different sets of sights. You are deciding whether to add the roof. Everything at ground level is the same on both tickets. Neither one leaves out the Library, the Museum, the Crypt or the Baptistery. The real questions are about you: how you feel about heights, what you are carrying, who is with you and how much time you have.

What does the time on your ticket mean?

On the Gate of Heaven ticket, the time is the start of your roof visit. The walk lasts 30 minutes, and Cathedral staff go with each group for safety. Groups are small, with up to 18 people on each walk. On a typical autumn day, departures run every half hour. You meet at the main entrance of the Cathedral, in the priority queue, at least 20 minutes before your time.

Treat those 20 minutes as part of the booking. If you arrive late at the meeting point, the operator gives no refund for the roof ascent. Plan the rest of your day around the roof time rather than squeezing the walk in between other stops. Have lunch after the climb, not before it. Leave the Museum or the Baptistery for later, when the fixed part of your visit is done.

On the OPA SI pass, the time is your entry into the Cathedral. The operator asks that it is respected, so think of it as an appointment. The time applies to the Cathedral only. The Museum, with its panorama, the Crypt and the Baptistery can be visited whenever suits you within the ticket's validity, during their opening hours. That makes the OPA SI pass the looser of the two tickets to plan around.

How long are the tickets valid, and what comes with them?

Both tickets are valid for three consecutive days. That matters more than it sounds. The complex is large, and trying to see all of it in one go can blur the Library into the Museum and the Museum into the Crypt. With three days, you can split it. Do the Cathedral and the roof one morning, then come back the next afternoon for the Museum and the view from the New Cathedral façade.

Both tickets also come with a free audio guide that plays on your own smartphone. Bring headphones and a charged phone, and perhaps a small power bank. Your e-ticket arrives by email, so it can sit on the same phone. If you are going up to the roof, the rules ask you to carry phones, cameras and glasses on a strap. A cheap lanyard or wrist strap is worth packing before you leave home.

Three days also let you work with the weather and the crowds. If the morning is grey, save the panorama from the New Cathedral façade for a clearer hour. If the Cathedral feels busy, step across to the Baptistery or down to the Crypt and come back later. Keep your e-ticket handy at every door, because the same ticket covers each site. The days are consecutive, though, so they cannot be spread across a longer trip with gaps in between.

Which ticket should families with children choose?

The roof ticket has its own child line. Children aged 7 to 11 have a reduced Gate of Heaven ticket. Children up to 6 are free, added to your booking at no charge. The operator sets no minimum age for the roof walk. Its rules do ask adults to hold young children by the hand along the route, which is sensible advice in narrow attic passages.

On the OPA SI side, our booking covers adult tickets only. We do not book a child line for that pass. If you are travelling with children and want their tickets in the same booking as yours, choose the Gate of Heaven ticket. It gives them the full complex at ground level as well as the roof, so nobody in the family misses the Library or the Baptistery.

Think about the children themselves, too. The roof is reached by a winding staircase, and some passages have low ceilings. A steady eight-year-old who likes climbing will probably enjoy it. A tired toddler at the end of a long day may not. Closed-toe shoes with a good grip are advised for everyone on the roof, children included, so leave the sandals at the hotel.

Who should choose the Gate of Heaven roof ticket?

Choose the roof if you like seeing how a building works. From the attic you look down into the church from above and out across the rooftops. The route described at the 2013 opening goes up past the two towers of the façade. It then runs above the starred vaults of the right aisle and through internal galleries that look down to the high altar and the copy of Duccio's round window.

From there, the route takes you along the left side, with views out to San Domenico, the Medici Fortress and the countryside. It continues to a gallery around the dome and ends on the gallery inside the façade. A room along the way shows tools used to build the Cathedral. The operator's own description is shorter: above the vaults, with views inside and outside. The exact order today may differ from 2013.

Choose it, too, if you have been to Siena before. If you already know the nave, the Library and Nicola Pisano's pulpit, the roof gives you a new angle on a building you thought you knew. First-timers lose nothing by adding it either. The ticket includes the whole complex, so you still see the 172 busts of popes along the cornice and Michelangelo's early statues on the Piccolomini Altar from floor level.

When is the OPA SI pass the better choice?

Choose the OPA SI pass if heights or tight spaces trouble you. The operator does not recommend the roof walk for people with heart conditions or dizziness, or for anyone not fit to climb to raised places. There is no reason to push yourself. The Cathedral's black-and-white marble, the blue and gold vaults and the Library frescoes are all at ground level, and they fill a morning on their own.

Choose it if you are carrying luggage. Backpacks and large, bulky bags are not admitted on the roof, and there is no deposit for personal belongings anywhere in the OPA complex. Only umbrellas can be left at the staircase. High heels are refused, and flip-flops, sandals, clogs and leather soles are discouraged. If you are arriving on a day trip with a suitcase or wearing the wrong shoes, the pass without the roof is the practical pick.

Choose it if your time is tight. The roof adds a fixed 30-minute walk, plus the 20 minutes you spend at the meeting point beforehand. On a day trip from Florence, where the fastest bus takes about an hour and a quarter each way, that block of nearly an hour can matter. The OPA SI pass leaves only your Cathedral entry time fixed, so the rest of the day stays flexible.

And between 7 January and the end of February, the OPA SI pass is the only choice. The roof walk is closed in those weeks and reopens on 1 March. The rest of the complex stays open through the winter, with shorter hours. If your trip falls in that window, there is nothing to decide. Book the pass and spend the time you save in the Library.

How do Sundays and the season change your choice?

Sundays and public holidays have shorter hours, because the Cathedral is a working church. For most of April to October, it opens on Sundays at 13:30 and closes at 18:00. The roof follows Cathedral hours, so a Sunday gives you fewer roof times to choose from. Last admission is 30 minutes before closing, and hours can change for religious services. If you have a choice of days, a weekday is easier to plan.

The season also changes what you see inside. For part of each year, the Cathedral's marble floor is uncovered. It is made of 56 inlaid panels created between the 14th and 19th centuries, including Pinturicchio's Mount of Wisdom and Beccafumi's panels under the dome. In 2026 the floor is uncovered from 27 June to 31 July and from 18 August to 15 November. For the rest of the year, the panels are largely kept under protective covering.

The floor season changes Sundays too. While the floor is uncovered, Sunday Mass moves to the church of Santissima Annunziata and the Cathedral opens on Sundays from 9:30. The floor is in the Cathedral, so you see it on either ticket. It is also a busy time. In early October 2026, the first two Sunday roof times had sold out three days ahead. If your dates are fixed, book the roof early.

A quick way to decide between the two tickets

Ask yourself three questions. Are you comfortable with heights, narrow passages and a winding staircase? Can you leave big bags and backpacks behind for the visit? Do you have time for a fixed 30-minute walk, with 20 minutes at the meeting point before it? If the answer to all three is yes, and you are visiting between 1 March and 6 January, take the Gate of Heaven ticket.

If any answer is no, the OPA SI pass gives you the Cathedral, the Piccolomini Library, the Museum and its panorama, the Crypt and the Baptistery, with three days to see them. Families who want child tickets in their booking should take the roof ticket either way. And if you are simply unsure, remember that the roof ticket includes everything else, so choosing it costs you no part of the complex.
