Stand in this magnificent square and spin 360 degrees. You've just taken in an overview of Pienza's major monuments. Gems of the Renaissance constructed in a mere three years between 1459 and 1462, they're arranged according to the urban design of Bernardo Rossellino, who applied the principles of Renaissance town planning devised by his mentor, Leon Battista Alberti.
The space available to Rossellino was limited, so to increase the sense of perspective and dignity of the great edifices he'd been commissioned to design, he set them off at angles to the cathedral around a magnificently paved piazza. It was a true masterstroke, something acknowledged by Unesco through a World Heritage listing.
