Florence or Firenze as I prefer to call it, is probably my favourite place I have visited in Italy (so far). I was there in 2006 on a short visit and would have loved to have stayed much longer.
The Ponte Vecchio is the oldest bridge in Florence and is rumoured to have been in existence in Roman times. It still has shops and apartments built on the bridge that are in use today. It is also the only bridge across the Arno river that escaped destruction during WWII.
When I think of Florence I think of DaVinci and Michelangelo as they used to ‘hang out’ in the city. Fascinating to walk around the small streets and piazzas gazing at the architecture thinking of them doing the same hundreds of years ago. With only a short visit it was difficult to choose what to see as there are so many galleries and also so many tourists but waiting in the queue to see the Uffizi and the Academia Galleries was worth it. Our visit was in April so the big tourist boom of the season was just beginning; a few weeks later and I am sure the wait would have been much longer.
The Uffizi Gallery https://en.wikipedia.org/wiki/Uffizi and the Academia Gallery http://www.accademia.org/explore-museum/artworks/michelangelos-david/ where the original sculpture of Michelangelo’s David is kept. Yes the original David. And it really is spectacular.
The Leonardo DaVinci Museum was also fabulous http://www.museumsinflorence.com/musei/Leonardo-museum.html I think most of the magic comes from the ambience of Florence itself. To walk the streets where the great masters would meet for a drink, philosophize about life and discuss their latest ‘projects’ is simply a very cool feeling to experience.
South of the river are the beautiful Boboli Gardens https://www.visitflorence.com/florence-museums/boboli-gardens.html and the Buontalenti Grotto http://www.atlasobscura.com/places/the-buontalenti-grotto
There was a great outdoor market we would wander through each day I think it was close to the Florence Cathedral or Duomo. I remember the fine quality of leather goods and fairly reasonable prices and with some bartering, even more affordable. I still use a leather purse and jacket I purchased and they do not look much different than when I purchased them over 10 years ago.
Enjoy!
