Tokyo Tower of Babel

proposed building in Japan

The Tokyo Tower of Babel (Japanese: 東京バベルタワー) is a visionary 10 km hyper tall building that was proposed to be built in Tokyo in 1992. Although it is unlikely to ever be built in the future. If it actually was built, it would be the tallest building on Earth surpassing Mount Everest by 1,152 metres. It would take 100 to 150 years to build, it would house about 30 million people within if it was ever built.
