  • Replaced the Empire State Building as the city's and the world's tallest building.
  • World's tallest building from 1972-1974; surpassed by the Willis Tower in Chicago.
  • Windows of the World Restaurant (the world's highest) occupied the 107th floor.
  • One World Trade Center was ready for its first tenants in late 1970, though the upper stories were not completed until 1972.
  • Faced with the difficulties of building to unprecedented heights, the engineers employed an innovative structural model: a rigid "hollow tube" of closely spaced steel columns with floor trusses extending across to a central core.
  • The columns, finished with a silver-colored aluminum alloy, were 18 3/4" wide and set only 22" apart, making the towers appear from afar to have no windows at all.
  • Also unique to the engineering design were its core and elevator system.
  • Worried that the intense air pressure created by the buildings' high speed elevators might buckle conventional shafts, engineers designed a solution using a drywall system fixed to the reinforced steel core.
  • The twin towers were the first super-tall buildings designed without any masonry.
  • On 7th August 1974, French high wire artist Philippe Petit made an illegal tightrope walk back and forth between One and Two World Trade Center towers that lasted almost an hour.
  • The building was destroyed in the terrorist attacks of September 11th 2001, when a Boeing 767 was flown into the building at the 96th floor at 8:46 am. The building collapsed at 10:28 am.
