A visit with the audioguide allows you to discover the inner courtyard of this wonderful palace, built as an expression of the interrelations between man and nature. Wander through the hanging garden and the charming rooms of the Palazzo Piccolomini and the Palazzo Borgia, then enjoy a breathtaking view from the loggia over the Orcia Valley.  Palazzo Piccolomini was the summer residence of Pope Pius II, and is part of a complex that includes the cathedral and the square, commissioned by the Pope and built in 1459 by famed architect Bernardo Rossellino, student of Leon Battista Alberti. The rooms on the main floor are furnished with period furniture, paintings and other furnishings, testimony to a past that still remains intact. Part of the Bishop’s Palace together with the palace of Cardinal Francesco Jouffroy of Arras, Palazzo Borgia, once owned by Cardinal Rodrigo, future Pope Alexander VI, overlooks the square. Pienza is also known as having the first roof garden of the Renaissance, with views of the Val d'Orcia and Mount Amiata.
