Pienza is a town in Tuscany, Italy. The central Piazza Pio II is framed by 15th-century buildings like the Pienza Cathedral and Piccolomini Palace. The latter was Pope Pius II’s summer residence and features a roof garden with valley views. Flemish tapestries and the pope’s embroidered cape are on display at the Diocesan Museum. West is the Pieve di Corsignano, a Romanesque church with a circular bell tower.
