It was originally the Magistrates' Palace, as built by Giorgio Vasari "on the river, almost in the air;" in 1581 Grand Duke Francesco I de' Medici transformed the top floor of the palace into a gallery to house the crown jewels.
The gallery was itself created as a cabinet of curiosities, which means a place of wonders.

The most beautiful and most important cabinet of curiosities in Italy is in the Pitti Palace in Florence. In the northern part of the palace, known as the "Summer Apartment", is the Tesoro dei Granduchi, the "Treasury of the Grand Dukes", an extraordinary assemblage of rare and precious objects.

The kind of imagination which, in 1602, inspired Campanella's prose, is the same impetus that generated the culture of the cabinet of curiosities, a phenomenon that spread throughout Italy at this time as well as through the rest of Europe.
