Volterra on those dates - they have the medieval festival back on this summer - the first date is the 14th, so right after you arrive, the program isn't out yet but you can follow updates on their facebook page -

I am working on updating all the events - lots of them were cancelled for 2 summers and everyone is catching up and programming events this summer, you will find lots of events every single weekend if not more during that month! I cannot keep up with all the news, some stuff also comes up last minute on my radar and I'm a bit overwhelmed but hopefully with a week or two of hunkering down I will manage to get most of the stuff for the summer up to date.
