We were in Florence on the day of the Paris terror attack on November 19, 2015. Immediately, we noticed the presence of heavily armed police and soldiers in all of the most tourist frequented areas of the city. It was somewhat unnerving for us, but we spent the last 4 days of our two week trip doing/seeing everything we planned. We traveled back to Milan by train to see Michelangelo's Last Supper and to catch out flight back to Boston. We saw many more heavily armed soldiers in Milan, but thankfully there were no incidents.
