This week we revealed everything we know about mega-project Neom

This week on Dezeen, we compiled an explainer of all the key facts you need to know about the Neom development in Saudi Arabia and its megacity The Line, which is proving to be the most controversial architecture project in recent history. Set to occupy around as much space as the entire country of Albania, Neom will be split into 10 different regions including a floating port, a ski resort in the Sarwat Mountains and a mirrored city for nine million people formed from two linear skyscrapers. Our explainer breaks down everything from how the project is financed to what architecture studios are working on its various different components. Saudi Arabia also revealed another strange-shaped skyscraper this week in the form of a giant cube, which is set to be constructed in the capital of Riyadh. Measuring 400 metres high and 400 metres long on each side, the Mukaab building is set to become the city's tallest building and will house two million square metres of shops alongside cultural and tourist attractions.
