At the end of this treaty, there's a summary of annexes:
"fist annex: Map of the territory of Vatican City
second annex: Map of the buildings with extraterritorial privilege
and fiscal and expropiation exemption.
Third annex: map of the buildings with fiscal and expropiation
exemption."

Thanks for the translation. Yes, I too think that everything outside
of the Vatican walls is at least not sovereign Vatican territory. And
it confirms my believe that there are three flavours here, summed up
by the three annexes here. I would love to see good maps and/or up to
date lists of these territories.

The second and third kind are Vatican property, I think (or property
of the Holy See, to be more precise). Why else the protection clause
against expropriation?
