The completion date for the world‘s tallest tower has been pushed back to 2019, a Saudi Arabian billionaire said, almost six years after launching the record-breaking project.
Saudi‘s Jeddah Tower is to rise more than a kilometer, placing it above Dubai’s Burj Khalifa.
The world‘s tallest artificial structure is the 828-meter-tall Burj Khalifa in Dubai. The second-tallest self-supporting structure and the tallest tower is the Tokyo Skytree.
