Monaco is queezed into just 200 hectares, this principality might be the world’s second-smallest country (the Vatican is smaller), but what it lacks in size it makes up for in attitude. A magnet for high-rollers since the early 20th century, it's also one of the world's most notorious tax havens. It's also famous for its annual Formula 1 Grand Prix the one race of the year that every driver dreams of winning.
