Скачать или смотреть The $500 Billion Underground City NEOM Is Digging

Saudi Arabia is digging a city straight into the mountains—and it’s unlike anything the world has seen. Part of the $500 billion NEOM project, The Vault is a vertical, fully underground city in Trojena, designed to house homes, offices, parks, shops, and transport—all beneath one of the harshest deserts on Earth. In this video, we explore the bold engineering, climate control systems, and sustainable technologies powering this subterranean megaproject—and the enormous risks it faces.

Will this underground city become the future of urban life… or collapse under its own ambition?
