What does the Opa Si Pass include?
The pass gives you entry to seven sites of the Cathedral complex: the Duomo itself, the Piccolomini Library, the Crypt, the Baptistery of San Giovanni, the Museo dell’Opera, the Facciatone panoramic viewpoint, and the Oratory of San Bernardino with the Diocesan Museum. A multilingual audio guide is included via a free smartphone app.
How long is the pass valid?
From the first use, the pass is valid for 3 consecutive days. You can visit each site once, and you do not have to see them all in one day.
Is the Porta del Cielo (rooftop) included?
No. The Porta del Cielo — a guided tour along the roof and inside the vaults of the Cathedral — is a separate paid ticket (21 € for adults) and needs to be booked in advance.
When is the marble floor visible?
In 2026 the marble inlay floor is fully uncovered from 27 June to 31 July and again from 18 August to 15 November. In other periods large parts of the floor are covered by protective panels.
How do I exchange my voucher?
You can exchange the voucher at the ticket desk of the Cripta del Duomo (San Giovanni staircase), at Piazza Duomo 7, or at the Dear Guests Visitor Center in Via di Città 48. Show the QR code on your phone — no printout needed.
Do I need to book a specific time slot?
No. The Opa Si Pass is valid for 3 consecutive days from your first entry, and you do not need to reserve a fixed time slot for any of the seven sites. Just show up whenever it suits you and enter with your ticket.
What languages does the audio guide support?
The audio guide is available in Italian, English, German, French and Spanish. It runs as a free app on your smartphone — we recommend installing it before you enter the Duomo, as Wi-Fi is limited inside.
What is the difference between the Opa Si Pass and the Cathedral-only ticket?
The Opa Si Pass covers seven sites of the Cathedral complex and is valid three days. The Cathedral-only ticket covers just the Duomo and the Piccolomini Library. If you want to see the Crypt, Baptistery, Museum, Facciatone or the Oratory of San Bernardino, you need the pass.
