As a city-state in Europe, Monaco ranks to be the second smallest country (second to Vatican) worldwide having national territorial area being 1.95 square kilometers. However, it is one of the most densely populated countries in the world, and becomes world-famous for many rich people and F1 Grand Prix. Monaco, featuring ancient castles, thousands of sails, cars and girls, acrobatics and unrestrained gambling, is always smiling and shining, just like its past princess, Grace Kelly.
