shorter than its counterpart at the cathedral, to symbolize the superior power of the church. The set-back addition to the tower dates from 1599. It is likely that Bernardo Rossellino designed the Palazzo Comunale to be a free standing civic mediator between the religious space before the cathedral and secular market square to its rear. The travertine well in the Piazza carries the Piccolomini family crest, and was widely copied in Tuscany during the following century. The well-head resembles a fluted, shallow Etruscan Bowl. The flanking Corinthian support a classical entablature columns whose decorations are clearly based upon actual source materials. Other buildings Other buildings in Pienza dating from the era of Pius II include the Ammannati Palace, named for Cardinal Jacopo Piccolomini-Ammannati, a "curial row" of three palaces (the Palazzo Jouffroy or Atrebatense belonging to Cardinal Jean Jouffroy of Arras, the Palazzo Buonconti, belonging to Vatican Treasurer Giliforte dei Buonconti, and the Palazzo Lolli constructed by apostolic secretary and papal relative Gregorio Lolli) arranged along the street behind the Bishops Palace. along the main road there are also the Palazzo Gonzaga, built in 1463 by Cardinal Francesco Gonzaga, Palazzo Forteguerri built in 1460 by Ambrogio Fortguerri, Apostolic Treasurer, and the Palazzo of Ambrogio Spannocchi, now Cittadini, again of the XV century.

About fifty meters west of the Cathedral Piazza is the church of San Francesco, with a gabled facade and Gothic portal. Among the buildings that survived from the old Corsignano, it is built on a pre-existing church that dated from the 8th century. The interior contains frescoes depicting the life of Saint Francis, those on the walls having been painted by Cristofano di Bindoccio and Meo di Pero, 14th-century artists of the Sienese School. The Romanesque Pieve of Corsignano is located in the neighbourhood.

The refectory houses frescoes by il Sodoma (1502–1503). Monticchiello The frazione of Monticchiello is home to a characteristic Romitorio, a series of grottoes carved in the rock by hermit monks. In the same locality is the pieve
