Originally known of as "Castello di Corsignano", Pienza takes its current name from Pope Pius II Piccolomini, who, in the second half of the fifteenth century commenced the renovation works for turning it into a utopia of the ideal town. The entire hamlet is a tiny gem, a magnificent sight for the eyes, where special attention must be paid to the Duomo which houses works by Giovanni di Paolo, Matteo di Giovanni del Vecchietta, and Sano di Pietro; there is also a marble altar attributed to Rossellino, the architect who was entrusted the task by Pope Pius II of redesigning the city.
Next to the Duomo there is the "Diocesan Museum", where it is possible to admire works from the school of Sodoma and Sano di Pietro, Flemish tapestries from the sixteenth and sixteenth centuries.
A few metres further on, there's magnificent Palazzo Piccolomini, built to the design of Bronzino and Beccafumi. Downhill from the township is the enchanting countryside of the " Artistic, Natural, and Cultural Park of the Val d'Orcia", with its badlands, undulating meadows and famous clayey ridges.
