Features of the original towers

Before it's destruction, the Twin Towers were mostly office space, but there was a restaurant on the 107th floor of the North tower and an indoor and outdoor observation deck on the South tower.

Windows On the World

A restaurant on the 106th and 107th floors of the North Tower. It opened on April of 1976. The restaurant was developed by Joe Baum which cost more than $17 million. Was closed following the 1993 World Trade Center bombing and reopened in 1996. During 2000, the restaurant's last full year of operation, Windows On the World reported revenues of $37 million which made it the highest-grossing restaurant in the USA.

Top of the World

Was an observation deck on the 107th floor and roof of the South tower. After the 1993 terrorist bombing, visitors would have to pass through security checks, and then sent to the 107th floor indoor observatory. When the weather allows, visitors could ride two escalators up from the 107th floor to the outdoor observation deck on the roof. On a clear day, it is said that visitors could see up to 50 miles.

World Trade Center lobby

The lobby of the World Trade Center South tower


To get up to the 107th floor or any offices, a person would have to go through the lobby. After the 1993 bombing, turnstiles and extra security measures were installed, but that was not enough to stop another terrorist attack, since the next one involved hijacked planes. Elevators can be accessed from here.


Because of how tall the towers are and how many elevators were required, engineers decided to use a system with two "sky lobbies", basically floors where people can switch from express elevators to local elevators. They were located on the 44th and 78th floors of the Twin Towers.

1993 bombing

On February 26, 1993, Al-Qaeda terrorists tried to destroy the World Trade Center Twin Towers by parking a Ryder van into the public parking garage on underground level B-2. The bomb opened a 30-m wide hole through four sublevels of concrete. The bomb explosion instantly cut of electricity to the World Trade Center.


On September 11th 2001, terrorists from Al-Qaeda hijacked four planes and of course, two of them were flown into the Twin Towers of the World Trade Center.
