The Ryugyong Hotel in Pyongyang, North Korea

If Dr. Evil was a real person, he would need a real hideout, and that real hideout may very well be The Ryugyong Hotel in Pyongyang, North Korea.

The giant dark monolith is 1,082 feet tall, has 105 floors, yet it is completely empty without a single window.

The Ryugong Hotel must be "the single most unsettling structure ever erected by the hand of man".

One question that pops up often is, why does Ryugyong Hotel exist in the first place? Certainly it is not to meet North Korea's mounting tourist demand. The hotel was designed to have 3,000 rooms, yet if every single Pyongyang area visitor booked a weeklong stay, the hotel would still be hanging a vacancy sign on the front door.

So why did North Korea build this not-so-secret-hideout-type structure? We think it's gotta be national pride.

Unfortunately, it looks like national pride has gone terribly wrong. The North Korean's started this project back in 1987 and have spent around $750 million or 2% of the country's GDP on the Ryugyong Hotel.
