Adm
Combo Pass: Covers entire Duomo group for half-price. » book

Planning your day: Give the cathedral itself at least 30 minutes.

Siena Cathedral Combo Pass - The pass covers entry to the entire Duomo grouping for about half the cost of individual admissions to: the Duomo's (normally €3; or €6 when the panels are uncovered), Crypt (€8), Baptistery (€3), Museo dell'Opera (€6), and Oratorio of San Bernardino (€3). » book

The famous floor panels of the Duomo are usually covered to protect them (save a few roped-off sample panels).

However, from August 21 to October 21, they uncover the entire floor. It is pretty spectacular—though the admission price to the Duomo does double whenever the floor is uncovered.

Services are held Sundays at 8am, 11am, 12:15pm, and 6pm (7pm in summer).
