Video reveals 170-kilometre-long mirrored skyscraper The Line in Saudi Arabia

This video unveils the design for The Line, a 500-metre-tall mirror-clad skyscraper that will be built to house nine million people as part of the Neom initiative in Saudi Arabia.

The linear city, which will be 170 kilometres long and 200 metres wide, was launched by Saudia Arabia's crown prince Mohammed bin Salman and is described as "a revolution in civilization."

It will have a footprint of just 34 square kilometres and house nine million people, who will live in neighbourhoods where all daily needs are accessible within a five-minute walk.
