Here’s the first floor of the sacristy finished. It’s occupied by the Vatican Archives and the workshops of the Fabbrica di San Pietro, which is the organization responsible for the maintenance of St. Peter’s Basilica.
Okay, I’m gonna get back to work on the third and final floor. Be back with that before long!
By the way, If you want to see the rest of my Vatican City maps, you can find them all here.
