One Kilometer High Building in the World Jeddah Tower
Jeddah Tower (Arabic: برج جدة),[9] previously known as Kingdom Tower(برج المملكة) and Mile-High Tower (برج الميل), is a skyscraper under construction in Jeddah, Saudi Arabia, at a preliminary cost ofSR4.6 billion (US$1.23 billion).[10] It will be the centrepiece and first phase of a SR75 billion (US$20 billion)[11] proposed development known as Jeddah Economic City that will be located along the Red Sea on the north side of Jeddah. If completed as planned, the Jeddah Tower will reach unprecedented heights, becoming the tallest building in the world, as well as the first structure to reach the one-kilometre-high mark. (Initially planned to be 1.6 kilometres (1 mi) high, the geology of the area proved unsuitable for a tower of that height.)
