The original World Trade Center was a large complex of seven buildings in Lower Manhattan, New York City, United States. It featured the landmark Twin Towers, which opened on April 4, 1973, and were destroyed in 2001 during the September 11 attacks.
At the time of their completion, the Twin Towers—the original 1 World Trade Center, at 1,368 feet (417 m); and 2 World Trade Center, at 1,362 feet (415.1 m)—were the tallest buildings in the world. Other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex was located in New York City's Financial District and contained 13,400,000 square feet (1,240,000 m2) of office space.
Take a look at these pictures to remember the memories of the Twin Towers and the feelings when you've been standing on top of them from the 1970s.
