Florence is an amazing city that is well known for its history and its art. On our trip, we will have one full free day to wonder the city and to marvel at its wonders so in prep for that I have posted a few things. The first item you will see is a sightseeing itinerary from Rick Steves. Follow what you like or none of it at all, but he has some suggestions for some really great things to see. Follow this link for his itinerary: http://www.ricksteves.com/plan/destinations/italy/florence3.htm
The Uffizi Gallery is one place you might like to check out to admire some amazing art:
Here is a little bit about the Duomo – the Cathedral of Florence. If you are adventurous, and in shape, you can make your way up to the top of the Dome.
If you are wanting to get away from the main touristy parts of Florence and get into the local culture, here is a video and some suggestions for you.
