Saudi Arabia has revealed design plans for a meandering, mirrored megacity.
Dubbed “The Line,” the project will be just 200 meters wide, but rise 500 meters into the sky and extend across 170 kilometres of desert and mountainous terrain. The whole thing will be clad in mirrors.

“The Line is a civilizational revolution that puts humans first, providing an unprecedented urban living experience while preserving the surrounding nature,” a release announcing the design reads.
“[The city] redefines the concept of urban development and what cities of the future should look like.”

“Unlike traditional cities,” The Line will prioritize people’s health and wellbeing over transportation and infrastructure. Comprised of two parallel buildings connected by walkways, it will run on 100% renewable energy and there will be no roads, cars, or emissions. Its water supply, too, will be 100% renewable.
The Line will have a reduced infrastructure footprint of just 34 square kilometres, and create “never-before-seen efficiencies in city functions.”
There will be a year-round temperate microclimate with natural ventilation. Services will be autonomous and leverage AI technology, according to a promotional video reminiscent of a sci-fi film.

Within its mirrored façade, The Line will utilize “Zero Gravity Urbanism”: city features and amenities – parks, schools, homes, and businesses – will be layered vertically and residents can move up, down, or across to access them. It will eventually house nine million people.
Residents can access all facilities within a five minute walk, and a high-speed rail will breeze from one end of the structure to the other in just 20 minutes.
A “revolutionary concept for the city of the future,” The Line will “create extraordinary experiences and magical moments.”
