Buzludzha Monument, Kazanlak, Bulgaria
The Buzludzha Monument was created during the Cold War by communist leaders to house the Bulgarian Communist Party. There, you’d find posters of Marx and Lenin and red stars all along the ceiling. In 1989, it was abandoned and closed, but many people would still sneak into the UFO shaped building.
Ryugyong Hotel, Pyongyang, North Korea
The Ryugyong Hotel in Pyongyany, North Korea was built to compete with the Westin Stamford Hotel in Singapore, which was the tallest hotel in the world. The idea was that North Korean leaders wanted to prove that they could outdo Singapore. The 105 story hotel began being built, but 30 years later and $750 million into the project, it remains unfinished.
