Siena Cathedral

Getting around: In central Siena, a 10-minute walk from Piazza del Campo.
Hours: Typically open daily, roughly 10:30am-5:30pm, with variations by season and reduced Sunday hours. Ticketed entry, often as part of a combined Opera della Metropolitana pass covering the crypt, baptistery, and museum.

Siena Cathedral is a 13th-century Gothic church distinguished by its striped black-and-white marble facade and interior, and by an elaborately decorated inlaid marble floor covering the entire nave with 56 different panels depicting biblical and allegorical scenes, created over roughly two centuries. Parts of the floor are only uncovered for public viewing during limited periods each year.

The cathedral was originally intended to be even larger, with an ambitious 14th-century expansion plan abandoned after the Black Death devastated Siena's population and finances; the unfinished wall of that planned expansion, the Facciatone, still stands nearby and can be climbed for views.

The complex also includes the Piccolomini Library with its Pinturicchio frescoes and a museum housing works originally created for the cathedral, making a full visit to the whole Opera del Duomo complex a substantial undertaking.
