Siena Cathedral

Siena Cathedral (Italian: Duomo di Siena) is a medieval church in Siena, Italy, dedicated from its earliest days as a Roman Catholic Marian church, and now dedicated to the Assumption of Mary.

Since its construction in the early 13th century, the cathedral has been central to Sienese identity. The cathedral complex was continuously expanded from its earliest days until the Black Death halted construction in 1348. The citizens of Siena continually advocated for the cathedral to become one of the largest churches in Europe.

The cathedral was designed and built between 1215 and 1263 on the site of an earlier structure. It has the form of a Latin cross with a slightly projecting transept, a dome and a bell tower. The dome, completed in 1264, rises from a hexagonal base with supporting columns.
