The Line

The Line (Arabic: ذا لاين) is a planned linear settlement under construction in Neom, Tabuk Province, Saudi Arabia, to be housed entirely in a single very long arcology. It is planned to be a smart city with no cars, streets or carbon emissions. The project was conceived by Saudi ruler Mohammed bin Salman, the leader of the project.

The initial plan called for the city to span 170 kilometres (110 mi) at a height of 500 m (1,600 ft) and a width of 200 metres (660 ft), with the capacity to accommodate a population of 9 million (25% of Saudi Arabia's 2022 population of 35.5 million). The Line was planned to have an entirely glass mirror exterior, with all basic services within a five-minute walking distance. The city is one of the five announced regions of Neom and is a part of Saudi Vision 2030 project.
