With an abundance of flashy casinos, luxury yachts, and exciting events (including the Formula One Grand Prix, the Monte-Carlo Arts Festival, and the Rolex Tennis Master), Monaco has been a top tourist attraction for years. Many of the world's wealthiest call this destination home...or at least vacation home. As a magnet for property tycoons, it's no surprise that Monaco could very soon be the home of the world's priciest property per square meter, which comes in the form of a multi-story penthouse in the Tour Odeon, ready to hit the market next year.
