What to Expect from the Tour

Starting at the “Meeting point” inside the Cathedral, you’ll be given your skip-the-line access, which is a real time-saver, especially during busy periods. The guided visit focuses primarily on the famous marble floor, which is only visible during brief periods when it’s uncovered—adding a layer of exclusivity and wonder to your visit. The guide’s insights help you appreciate the floor’s intricate mosaics, depicting biblical scenes and allegories, and explain why it’s such a treasured masterpiece.
Your guide will also introduce you to the crypt—a quiet, atmospheric space that offers a glimpse into the early Christian history of Siena—and the baptistery, with its beautiful frescoes and religious symbolism. The Museum of the Opera showcases artworks and relics associated with the Cathedral’s construction, giving context to the grand Gothic design.
Once inside, expect a mixture of awe-inspiring architecture, such as the soaring nave and the ornate facades, along with detailed commentary on the artworks and history. The Facciatone, the towering façade overlooking Siena’s rooftops, also offers panoramic views that many guides point out, though access may be limited depending on the day.
The Uncovered Marble Floor Experience

This is the main reason many travelers opt for this tour. The uncovered floor is only visible during select times of the year, making it a rare opportunity to see the detailed mosaics in their full glory. The guide will walk you through its history, artistic significance, and the stories depicted in the mosaics, enriching your appreciation. As one reviewer noted, their guide was “really knowledgeable,” making the visit memorable.
The Full Complex and Additional Monuments

The Opa Si Pass grants entry to several other parts of the Cathedral complex, including the Piccolomini Library, famed for its beautifully frescoed walls and ceiling, and the crypt, which offers a quieter, reflective space. The Baptistery is another highlight, with frescoes and intricate stonework. The Museum of the Opera displays artworks and relics related to the Cathedral’s construction, giving visitors a deeper understanding of Siena’s artistic heritage.
The Facciatone, the large terrace accessible from the church, provides sweeping views of Siena’s rooftops and countryside. Some guides might point out local landmarks from this vantage point, adding context to your visit.

The experience is not suitable for wheelchair users or those over 95, due to accessibility issues. Also, the strict rules on attire and behavior—no shorts, tank tops, large bags, or photography—are typical for religious sites, but it’s helpful to keep these in mind before your visit.
