Bowser's Castle is one of the most recognizable bad-guy pads in gaming history. It's hard to forget the first time you saw the massive, comically menacing structure, and knew you'd have to guide Mario through its maze-like levels filled with spinning columns of fire and dastardly koopas.
What if Bowser's Castle would go on the real life market? What is it worth? While Bowser's Castle isn't cheap, compared to other castles it's relatively affordable. A second, and more interesting fact, was that the Koopa King's real-life abode would be the tallest building in the world.
