Pienza is a small Tuscan gem that Pope Pius II transformed in the 15th century into an ideal Renaissance city, making it one of the most beautiful urban achievements of its time. Situated on a hilltop overlooking the Val d'Orcia valley, the city was inscribed on the UNESCO World Heritage List in 1996. Visit Pienza for its perfectly preserved architecture, its famous local pecorino cheese, and its breathtaking and unforgettable panoramas.
