Cathedral of Santa Maria dei Fiore
"Il Porcellino" ("piglet" in Italian) is the name of a boar-shaped fountain at this marketplace. Apparently, rubbing the boar's snout ensures a return trip to Florence. As you can see from the photo below, this tradition has worn away at the statue.
Piazza della Signoria
This is one of the main plazas in Florence, where I found the Palazzo Vecchio, Uffizi Gallery, Loggia dei Lanzi, and several famous sculptures.
The Old Palace
One of the oldest and most famous art museums in the world. Only a certain number of people are allowed inside of the museum at one time, so there was a long waiting line at the entrance. It took me about an hour and a half to get in.
Basilica of Santa Maria Novella
Loggia dei Lanzi
An open-air sculpture gallery in Piazza della Signoria of antique and renaissance art.
