Very easy to purchase tickets. The tour to see each of the exhibits was easy to follow. Each exhibit should be visited. The Duomo is amazing and hard to believe this was built 600+ years ago.

The ticketing experience was so easy and we were able to skip the line and get right in. This is the prettiest cathetedral we saw on our trip. It is just stunning and not to be missed. Go up to the roof for a wonderful view of Siena!

The Duomo complex was a fascinating and beautiful place to visit and gets 5 stars. The ticketing experience with Headout was average at best - given the mark-up over direct ticketing prices we had expected to be given detailed information on ticket collection (from when could they be collected), up to date opening hours and a detailed description of how the OPA Si pass works - especially with regards to the fact that several of the sites included have to be visited at the same time. There was essentially no information given by Headout and we were grateful for some very helpful local OPA staff who were able to guide us fully. I would not use Headout again for obtaining tickets that are available directly as there was no 'value-added'

Would be very helpful if you state what entity to pick up the tickets from. Was looking for a head out sign or person.

Journey into the heart of Siena Cathedral

Entry to the full Duomo Complex lets you soak in the grandeur of its uncovered floor, revealing intricate mosaics and fascinating stories. Listen to an audio guide that tells the tale of these grand halls, and marvel at the Piccolomini Library's collection of historic manuscripts. The walls are adorned with frescoes depicting 10 episodes from Pope Pius II's life, who was born into the Piccolomini family of Siena.

Art, culture, and hidden treasures

Continue to the Museo dell'Opera, home to some of the most precious works of art in Siena. The Crypt, which was hidden for 7 centuries, uncovers another layer of history with its well-preserved frescoes and relics. A visit to the Baptistry of San Giovanni is a must, as it houses a stunning baptismal font adorned with sculptures by renowned artists like Donatello and Jacopo della Quercia. Your OPA SI PASS is valid for 3 days, allowing ample time to explore at your own pace.
