A project for an underground working city in New York
During the Cold War, the U.S. prepared many bunkers capable of withstanding a nuclear strike. Cheyenne Mountain is one of the most rugged. It is a complex of 15 three-storey underground buildings. Structures able to withstand electromagnetic pulses, earthquakes and 30-megaton explosions.

In an effort to expand geography, people have learned to create incredible underground settlements. Perhaps in the near future, they will be the best way to connect parts of major cities.
This is truly fascinating! It’s incredible how underground cities have become a reality. I wonder, what were the main challenges faced in bringing these projects to life? How did they tackle issues like ventilation, lighting, or even psychological effects on residents?
