@twosidetrips: This is The Line, the biggest megaproject the world has ever seen. It would consist of 2 500-meter-tall skyscrapers stretching 170 kilometers through Saudi Arabia's desert. This is like building 2,000 One World Trade Centers twice! The insane project aims to create a linear city with mirrored exteriors and space for over 9 million people. The Line is part of Saudi Arabia's plan to shift the economy towards tourism and technology. However, it's highly questionable if they manage to build The Line and if such a building is even possible?
