Pienza, a town and comune in the province of Siena, in the Val d'Orcia in Tuscany (central Italy), between the towns of Montepulciano and Montalcino, is the "touchstone of Renaissance urbanism."
In 1996, UNESCO declared the town a World Heritage Site, and in 2004 the entire valley, the Val d'Orcia, was included on the list of UNESCO's World Cultural Landscapes.
Main sights
Palazzo Piccolomini
The trapezoidal piazza is defined by four buildings. The principal residence, Palazzo Piccolomini, is on the west side. It has three stories, articulated by pilasters and entablature courses, with a twin-lighted cross window set within each bay. This structure is similar to Alberti's Palazzo Rucellai in Florence and other later palaces. Noteworthy is the internal court of the palazzo. The back of the palace, to the south, is defined by loggia on all three floors that overlook an enclosed Italian Renaissance garden with Giardino all'italiana era modifications, and spectacular views into the distant 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. Though 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. Works of art in the duomo include five altar paintings from the Sienese School, by Sano di Pietro, Matteo di Giovanni, Vecchietta and Giovanni di Paolo. The Baptistry, dedicated as usual to San Giovanni, is located next to the apse of the church.
Palazzo Vescovile
Pius encouraged his cardinals to build palazzi to complete the city. Palazzo Vescovile, on the third side of the piazza, was built to house the bishops who would travel to Pienza to attend the pope. Its construction was financed by Cardinal Rodrigo Borgia (the future Pope Alexander VI but, at the time, Vatican Vice-Chancellor). It may represent a remodeling of the old town hall of Corsignano. It is now home to the Diocesan Museum,[3] and the Museo della Cattedrale. 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. When Corsigniano was given the status of an official city, a Palazzo was required that would be in keeping with the "city's" new urban position, though it was certainly more for show than anything else. 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 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, 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. In the northeastern corner of Pienza is a series of twelve row houses constructed at the orders of the pope by the Sienese building contractor Pietro Paolo da Porrina.
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 monastery of Sant'Anna in Camprena was founded in 1332-1334 by Bernardo Tolomei as a hermitage for the Benedictines; it was remade in the late 15th-early 16th century, and several times in the following centuries. The refectory houses frescoes by il Sodoma (1502–1503).
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 of Santi Leonardo e Cristoforo, rebuilt in the 13th century in Gothic style. The interior has frescoes from a 14th-century Sienese painter, a cyborium in the shape of a small Gothic portal and an alte 15th-century Crucifix. At San Pietro in Campo are the remains of the eponymous abbey.
