The Piazza della Signoria in Florence has been the center of the city's political life since the 14th century and was the site of important historical events like the return of the Medici family in 1530. The sculptures in the piazza, including Michelangelo's David, were chosen to convey political messages supporting or opposing the Medici. The Loggia dei Lanzi, an open-air sculpture gallery designed in 1376, houses statues like Cellini's Perseus that symbolized the fate of those who crossed the powerful Medici family.
