Here in Italy many small villages and towns are either having their annual festa or preparing for it as June and July are very popular times to hold them.
A lot of them are themed around a food item as you can see from two of the posters below. No food item is above a festa. Polenta, celery, potatoes you name it, it will probably have a festa in it's honour.
Our local village, Trevi, has its festa in October when the famous black celery of Trevi is celebrated. More of that come October.
Otherwise as the "Piccione' poster shows, they are just an excuse for a good time.
