Jeddah Tower (Arabic: ??? ????), previously called Kingdom Tower (??? ???????), is a stalled construction project of a skyscraper on the north of Jeddah, Saudi Arabia. It is supposed to be the world's first 1 km (3,281 feet ) high building, and the centrepiece and first phase of a development and tourist attraction called Jeddah Economic City.There was steady progress but in January 2018 building owner JEC halted structural concrete work together with the tower about one-third completed because of labour issues with a builder after the 2017--19 Saudi Arabian purge. JEC has said they plan to restart construction in 2020. The design, created by American architect Adrian Smith, who also designed the Burj Khalifa, incorporates many unique structural and aesthetic features. The founder and leader of the project is Saudi Arabian prince Al-Waleed bin Talal, a grandson of Ibn Saud, and nephew of the Kings of Saudi Arabia before him. Al-Waleed is the chairman of Kingdom Holding Company (KHC), which is a partner in the Jeddah Economic Company (JEC), which was formed in 2009 for the development of Jeddah Tower and City.
