Pienza is pretty. Pienza is very little. Pienza is WHS with OUV that is rather philosophical, I would say. Pienza is located on a hill, so, there are beautiful views on the Orcia valley (another WHS) and towards Monte Amiata (photo), which is also worth-visiting: The Monte Amiata mountain is covered by thick beech and chestnut forest, and the open-air thermal baths can be visited in Bagni San Filippo at the foot of the mountain, and... freshly proposed TWHS Via Francigena crossed Monte Amiata in Abbadia San Salvatore! It is not necessary to say more about Pienza, all basic data is given already in other reviews. There is actually only one square (Piazza Pio II) and ca. 4 buildings (Cathedral, Palazzo Piccolomini, and several others palaces) that deserve attention. However, it is enough to make Pienza so special. Besides the architecture, food is also very delicate in Pienza.
