Saudi Arabia has unveiled plans to introduce an eco-friendly megacity dubbed 'The Line'.
The project features a unique design, taking the shape of a mirrored sky scrapper that stretches 170 kilometres.
Saudi Arabia's Crown Prince Mohammed bin Salman revealed the city will run 100 per cent on renewable energy.
The project was met with mixed responses by Twitter users as questions over the 'The Line's' cost and timeline remain unresolved.
