The Most Serene Republic of San Marino, is an independent microstate surrounded by Italy at the northeast edge of the Apennine Mountains--essentially, a country within a country. It can stamp your passport and supply you with San Marino postage stamps. It covers only 24 sq mi but has a population of over 33,000, and has more vehicles than citizens. San Marino has the smallest population of all the members of the Council of Europe. Interesting to watch is a special team from their tiny army demonstrating their prowess with the crossbow.
