Vasari Corridor

I’ve been checking too since we’ll be in Florence early Septembrr. Google said May 24, but the website says check back.

Its page on the official website contains the current info:

A couple of articles out there in Italian indicate that it's unlikely to re-open until September or even later. Here's one of them:

I was in Florence in April, and the Vasari corridor was not open, and in fact looked like it wouldn't open anytime soon...

I was there the weekend of the 24th of May-not open nor did it look like it would be open soon.
