landscape of the Val d'Orcia and Pope Pius's beloved Mount Amiata beyond. Below this garden is a vaulted stable that had stalls for 100 horses. The Duomo The Duomo (Cathedral), which dominates the center of the piazza, has a facade that is one of the earliest designed in the Renaissance manner. Although the tripartite division is conventional, the use of pilasters and of columns, standing on high dados and linked by arches, was novel for the time. The bell tower, however, has a Germanic flavor as is the layout of the Hallenkirche plan, a "triple-nave" plan where the side aisles are almost as tall as the nave; Pius, before he became pope, served many years in Germany and praised the effects of light admitted into the German hall churches in his Commentari.

The collection includes local textile work as well as religious artifacts. Paintings include a 12th-century painted crucifix from the Abbey of San Pietro in Vollore, 14th century works by Pietro Lorenzetti (Madonna with Child) and Bartolo di Fredi (Madonna della Misericordia). There are also important works from the 14th and 15th centuries, including a Madonna attributed to Luca Signorelli. Palazzo Comunale Across from the church is the town hall, or Palazzo Comunale.

It has a three-arched loggia on the ground floor facing the Cathedral and above it is the council chamber. It also has a brick bell tower that is
