This magnificent palace was the residence of Pope Pius II, and is considered Bernardo Rossellino's masterpiece. Built on the site of the pope's family houses, it features a fine courtyard, handsome staircase and the former papal apartments, which are filled with period furnishings and minor art. Guided tours leave every 30 minutes; peeking into the courtyard is free.
To the rear, a three-level loggia offers a spectacular panorama over the Val d'Orcia far below.
