Step off the bustling Banchi di Sotto into the peaceful courtyard of Palazzo Piccolomini, a stunning example of Renaissance architecture right in the heart of Siena. While this grand palace now houses the State Archives, you can still admire its harmonious design and soak in the scholarly atmosphere. It's not a museum, but a living piece of Sienese history, offering a quiet moment of reflection and a perfect photo opportunity just a stone's throw from the Piazza del Campo.
