The "Diladdarno" is the area of Florence that extends along the left bank of the Arno River. It also happens to be my neighborhood. Tonight we are very excited to be attending San Frediano a Cena, the Premio "Torrino d'Oro", and open air dinner and awards ceremony held in the Piazza Cestello. More information on this event is available here, Italian only.
There is also a website for the Diladdarno where you can find information on events, shops, life in the area, and many other interesting things.
For example, this weekend there is both a concert in Piazza del Carmine on Saturday night, and the "Diladdarno in festa" on Sunday from 11 AM until 9 PM. All shops will be open, and there will be artisans, markets, and different events and shows in various piazzas.
