The World's Littlest Skyscraper
Completed in 1919 this squarish building isn't even close to the height of a skyscraper. Its name comes from a swindle that the architect pulled. His clients thought he was building a world-class skyscraper and...well...he wasn't. He disappeared with over $200K which would be almost $3 million today. Visitors are allowed inside the building.
