The World Trade Center in New York City, designed by Minoru Yamasaki, is a complex of seven office buildings and an underground shopping concourse.

What makes the World Trade Center famous is the two towers, 1 WTC and 2 WTC.

WTC 1 features Windows on the World, a restaurant with a view of Manhattan. WTC 2 features two observation decks -- indoors on the 107th floor and outdoors above the 110th floor, more than 1,300 feet above the city.

On a clear day, visitors can see more than 55 miles. On the open promenade at the top it can be windy at times. \plain\lang1024\f3\fs23

The WTC in itself is larger than many cities, population and activity-wise. It includes a multitude of restaurants and various services, as well as a shopping mall and a world class hotel.
