The tallest building in the United States, the One World Trade Center, opened on November 3 in New York. The building is 1,776ft (541m) tall, making it the 3rd tallest (completed) building in the world. It has 104 stories. The building stands in the area where the twin towers of the World Trade Center once stood. On September 11, 2001, a group called al-Qaeda staged an attack in the United States, destroying these twin towers and killing nearly 3,000 people. It took 8 years to construct the new One World Trade Center. Does the height of the building in feet ring a bell to all you history buffs? The number is the year the United States declared its independence from Great Britain.
One issue with such a tall building is how one cleans windows way up there. Well, a platform hangs from cables, and workers on the platform clean windows. On November 12, while two men were busy cleaning windows, a cable of the platform broke near the 68th floor. The two men were rescued by cutting a hole in the glass window.
The two tallest (completed) buildings in the world are the Burj Khalifa in Dubai, UAE and the Makkah Royal Clock Tower in Mecca, Saudi Arabia.
