The tallest Building in the United States, the One World Trade Center, opened on November 3, 2014 in New York. The building is 1,776 feet tall, making it the 3rd tallest building in the world. It has 104 floors. The building stands in the area where the twin towers of the World Trade Center once stood. On September 11, 2001, a group of terrorists destroyed these twin towers and killed nearly 3,000 people. It took 8 years to build the new One World Trade Center. Does the height of the building in feet reminds you of something in history? The number is the year when the United States declared(宣布) its independence (*)from Great Britain.

One problem with such a tall building is how to clean the windows. Well, a platform(平台) hangs from ropes, and workers on the platform clean windows. On November 12, while two men were busy cleaning windows, a rope of the platform broke near the 68th floor. The two men were saved by cutting a hole in the glass window.

The two tallest buildings in the world are the BurjKhalifa in Dubai, UAE and the Makkah Royal Clock Tower in Mecca, Saudi Arabia.
