At the fifth smallest country in the world, San Marino also has the distinction of being one of only three nations completely surrounded by another nation (Vatican City and Lesotho being the other two) and of being the only nation on earth where cars outnumber people.  Named after the Third Century Roman/Croatian stonemason Saint Marinus, San Marino also likes to think of itself as being the oldest extant sovereign state as well as the oldest constitutional republic, in addition to having the earliest written governing documents still in effect (the Constitution of San Marino, established in the 16th Century).  Packs a lot of punch, does our Most Serene Republic.
