Some of the most famous buildings in the world, such as the White House or the Waldorf Astoria hotel, actually have secret rooms. There are many reasons why these rooms exist. Some were built or used for secretive purposes, but others are just ordinary spaces that happen to be connected to architectural icons.
Either way, these secret rooms are the subjects of fascination. One reason why is because so few people actually get to see them. These rooms are usually off-limits to the public, and to visit them you need the right connections - it definitely helps if you're famous. Even if some of these rooms are little more than glorified broom closets, the fact that most aren't allowed to see them makes them intriguing.
