Vasari Corridor

As far as I know it hasn't re-opened and no specific date has been published yet for when that will happen.

As the Uffizi website (the Corridor is part of its museum collection) states:

All users are asked to check this web page about official news and
info concerning the upcoming opening and the new admission rules of
the Vasari Corridor.

I was in Florence last year and it wasn't open and the status was the same vague "soon".

According to a post here by Dario along with all the usual complications the renovation revealed bodies (hopefully ancient) and that excavation has added an unknown amount of additional delay.

Someday,
