22. Seborga, Italy

A village in the Italian Alps that styles itself as a principality, with its own (elected) monarch, currency (the luigino), and possibly Europe's highest cats-to-people ratio. It's one of the world's largest and most credible micronations (an entity that claims sovereignty without the means or desire to pursue actual independence).

Seborga is also associated with the Knights Templar, depicted in murals throughout the village, whilst their national holiday, St Bernard's Day on 20 August, is dedicated to the order's patron saint.
