About us

sienapass.com is a multilingual information and purchase site for the OPA SI PASS. The OPA SI PASS is the official combined ticket for Siena's cathedral complex. It is issued by the Opera della Metropolitana di Siena, the body responsible for the cathedral complex. The pass combines admission to the Gothic cathedral, the hidden crypt, the Piccolomini Library and the panoramic view from the Facciatone on a single ticket.

Siena's cathedral hill is a single complex with several ticket desks. The choice here is therefore not between sights but between separate tickets and one ticket for all of them. We write down which stations the pass ties together, what it expressly leaves out, such as Santa Maria della Scala across the square and the guided tours on the cathedral terraces, and how you exchange your voucher for a ticket at the visitor centre in Via di Città.

What this site is not

sienapass.com is an independent guide. We are not the official website of the Opera della Metropolitana di Siena. We are not a hotel or general travel portal, and we deliberately leave out a general Siena travel guide, restaurant recommendations and tours without a connection to the pass. We do not sell the pass ourselves: bookings are completed with our partner Tiqets, and their current prices, availability and terms apply.
