Begin the Chronicle
The History of the World Trade Center
The World Trade Center was more than a collection of buildings. It was an ambitious architectural and engineering project that transformed Lower Manhattan and became one of the most recognizable landmarks in the world.
Its history spans decades, from the first visions of an international trade center to the construction of the Twin Towers, the life of the original complex, the bombing of 1993, the attacks of September 11, 2001, and the creation of a new World Trade Center.
This chronicle follows that history step by step, placing the buildings, the people, the engineering, the events and the transformation of Lower Manhattan within their historical context.
