The World Trade Center was a complex of buildings constructed in Lower Manhattan, New York City, United States, replacing an earlier complex of seven buildings with the same name on the same site. The original World Trade Center featured landmark twin towers, which opened on April 4, 1973, and were destroyed in the September 11 attacks of 2001, along with 7 World Trade Center. The other buildings in the complex were severely damaged by the collapse of the twin towers, and their ruins were eventually demolished. The site is being rebuilt with six new skyscrapers, a memorial to those killed in the attacks, and a transportation hub. One World Trade Center, the tallest building in the United States, will be the lead building for the new complex, reaching more than 100 stories at its completion.

At the time of their completion, the "Twin Towers" — the original 1 World Trade Center (the North Tower), at 1,368 feet (417 m); and 2 World Trade Center (the South Tower) — were the tallest buildings in the world. The other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. All of these buildings were built between 1975 and 1985, with a construction cost of $400 million ($2,300,000,000 in 2014 dollars).[17] 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.

I have had the opportunity to visit the World Trade Center pre 911 and most recently, May 2014, post 911 which truly gave it new meaning. Exactly 13 years ago, the World Trade Center was destroyed by a network of terrorists that focused their intentions on disrupting the United States and World for their own cause. It took more than two (2) years to build and less than (5) hours to destroy.

We are too quick and easy to trust people around us. In the society we live in, we need to know who we are dealing with and ask the tough questions of who they are, why are they there, what they want from us and how can they help or hurt us.
