In 2009 we spent a month in Florence in an apartment just off this piazza. My wife and I would make a lunch and sit on the steps of the church and observe the activity in the piazza and I would sketch. Every day was something different. In this sketch they were setting up tents for a market for the next day. Another day they had a huge set-up for a marathon race. In the photo you will notice a curb like oval. This was the track used for chariot races in the day.
