Pienza owes its appearance to Pope Pius II (1405–64), who had grand plans to transform his hometown of Corsignano—its former name—into a compact model Renaissance town. The man entrusted with the transformation was Bernardo Rossellino (1409–64), a protégé of the great Renaissance architectural theorist Leon Battista Alberti (1404–72). His mandate was to create a cathedral, a papal palace, and a town hall that
adhered to the vainglorious pope's principles. Gothic and Renaissance styles were fused, and the buildings were decorated with Sienese paintings. The net result was a project that expressed Renaissance ideals of art, architecture, and civilized good living in a single scheme: it stands as an exquisite example of the architectural canons that Alberti formulated in the early Renaissance and that were utilized by later architects, including Michelangelo, in designing many of Italy's finest buildings and piazzas. Today the cool nobility of Pienza's center seems almost surreal in this otherwise unpretentious village, renowned for its smooth sheep's-milk pecorino cheese.
