This is the perfect recipe: Take the city of Monaco, put it on a giant yacht and you?ll have a $1 billion vessel fit for an actual king.

The concept was created by Yacht Island Design and it?s 500-foot long. Based on the actual city of Monaco, the yacht includes actual scaled down versions of Monaco?s most famous buildings, including Monte Carlo Casino.

If gambling is not your thing, don?t worry! There?s plenty of things to do, like drive around the Grand Prix go-kart course, multiple swimming pools, library, cafes, spa, basketball/tennis courts that are also helipads, parking spaces for smaller yachts and even a personal submarine.

This yacht can be the host of 16 guests and staff of 70.
