Saudis unveil eye-popping plan for mirrored skyscraper eco-city

Officials say the Line will be 200 metres wide, 100 miles long and the world's most livable city by far'

A futuristic Saudi megacity is to feature two skyscrapers extending across a swathe of desert and mountain terrain, according to the latest disclosures on the project by the kingdom's de facto ruler.

The parallel structures of mirror-encased skyscrapers extending more than 100 miles, known collectively as The Line, form the heart of the Red Sea megacity Neom, a plank of Crown Prince Mohammed bin Salman's effort to diversify the Gulf state's oil-dependent economy.
