The city state has the same
climate as Rome: temperate, mild, rainy winters (September to mid-May)
with hot, dry summers (May to September).
Vatican City has no set
official language. Unlike the Holy See, which most often uses Latin for
the authoritative version of its official documents, Vatican City uses
Italian in its legislation and official communications. Italian is also
the everyday language used by most of those who work in the state.
Vatican euro coins are
issued by the Philatelic and Numismatic Office of the Vatican City State
and minted by Istituto Poligrafico e Zecca dello Stato (IPZS), in Rome,
Italy. The euro is the official currency of Vatican City.
