First visit: October 2000
Subsequent visit: March 2001, March 2010.
Visited: Vatican City
There isn't much I can say about this tiny spec of land that is considered independent, other than it is an easy point if you want to say you have been to more countries. St. Peter's really is impressive, but the queues to get into the museum are such that I doubt I will ever make it there.
Highlight: The Vatican stamp, so send something from its post office.
