There’s an alley dating back to the medieval period leading out of (or into?) the Piazza della Signoria. Called the Chiasso di Baroncelli, this alley has seen some history. If alleys could talk!

Let’s just think a minute the events this alley has withstood: 16th and 19th century city demolition and rebuilding, German mining during WWII, the infamous 1966 flood and so much more.
Bounded on the southern end, where it meets via Lambertesca, buildings shield the alley from sunlight.

Next time you are walking around the piazza, stop and take a look.
