1. World Trade Center The Towers & The Memorial

2. The presentation model of the World Trade Center

3. The Twin Towers At 110 stories each, 1 WTC (North Tower) and 2 WTC (South Tower) provided nearly 10-million-square feet of office space for about 35,000 people and 430 companies. Attracting around 70,000 tourists and commuters every day, they were the tallest buildings in New York City, and for a brief period upon their completion, they were the tallest buildings in the world. On a clear day, views extended 45 miles from the top of the towers in every direction – far enough to see all five New York City boroughs, New Jersey and Connecticut.

4. Twin Towers Facts Each weighed more than 250,000 tons, contained 99 elevators and had 21,800 windows. Each floor was an acre in size and there was enough concrete in the towers to build a sidewalk from New York City to Washington, D.C. The complex even had its own zip code: 10048. The Twin Towers were completed in 1973

5. Twin Towers Facts In February 1993, terrorists with links to an Islamist extremist group detonated explosives in a van parked underneath the WTC. Six people were killed and thousands were injured. On September 11, 2001, as part of a series of coordinated suicide attacks, two planes struck both towers. 2, 753 victims were killed in the attack on the WTC.

11. The Design

13. Questions to Consider: 1. What do you think is significant about the number and placement of the pools? 2. What is symbolic about deciduous trees? 3. Why did the designer include wide open spaces?
