Separate from the archeological museum, there was an exhibition of a bronze statue of Minerva/Athena that was originally found in Arezzo and has been in the Florence Archeological museum for years. It was a big exhibition focusing on the recent restoration of the statue. Look at this photo of this huuuge room... with basically just the one statue in it.
The restoration of the statue was done by none other than Renzo! My archeological conservation teacher. Here's a photo of Renzo at work from a video on the restoration that was on loop in the exhibition. I was pretty proud.
