The Vatican is the smallest sovereign state in the world, measuring only about 109 acres (44 hectares). It is ringed with centuries-old walls and entirely surrounded by the city of Rome. But it is a separate nation, formed in 1929 in a treaty with the Italian government.
This independence is the Vatican's most important secular feature because it protects the pope from outside interference.
Within the walls, there is some open space, but for Swiss Guards out for a jog, the size of the Vatican gives a whole new meaning to the idea of running "cross country."
Besides a tiny population of about 900, the Vatican has everything a normal nation might have: a police force, a newspaper, a postal service, even a soup kitchen for the poor.
There are a few atypical features in this cityhere, traffic jams can sometimes stretch up to ten cars long, and the Vatican is, perhaps, the only country in the world where the cash machines provide instructions in Latin.
