I was looking through some pictures of North Korea, and found pictures of this tower, man is it incredible.
Basically they built the structure and realized the contrete was crap so they had to abandon it, leaving even the crane at the top. The top rungs of the building are 7 rotating floors.
"The building should have been opened in 1989, by that time it could have been the tallest hotel in the world and the 7th largest skyscraper. North Korea have spent ~$750 million or 2% of the country's GDP on the Ryugyong Hotel."
