Florence, at the heart of the Italian Rennaisance, might seem like an open air museum to most visitors. The piazzas and buildings themselves are a testament of the history of architecture and of past eras. Florence's cathedral, churches and many palaces were designed, built and decorated by many of the most illustrious of artists of the time, from Brunelleschi to Michelangelo, and can be admired freely from the outside. But in order to see another side of Florence, the side the contains most of its treasures, you need to go indoors and visit at least one or two museums while you are here. There you will find the paintings, sculptures and frescoes imagined and created by the greatest minds of all time.
