The cathedral, or duomo, of Siena is a magnificent Gothic church built between 1215 and 1263. One of its main features is the unusual inlaid marble floor, 56 panels created in the 14th – 16th centuries that depict historical or mythological events. The entire floor is only uncovered for a couple of months each year. Other things not to miss are the Piccolomini Library, covered with frescoes by Pinturicchio, and the Chapel of Saint John the Baptist, painted with scenes from Saint John’s life. Many statues and works of art can be seen in the cathedral.
To get a bird’s eye view of the cathedral, take the Gate of Heaven tour. Then go under the cathedral to visit the crypt where you can see parts of the earlier church that was built on this site. Next to the cathedral, the 14th century baptistery has 15th century frescoes. Buy a Cathedral Combo Plus Pass to see all the sights in the cathedral complex.
