The original One World Trade Center (also known as The North Tower, Tower 1, Building One, or 1 WTC) was one of the twin towers of the original World Trade Center in New York City. It was completed in 1972, standing at a height of 417 metres (1,368 ft), and was the tallest building in the world until being surpassed by the Sears Tower in Chicago in 1973. It was distinguishable from its twin, the original Two World Trade Center, also known as the South Tower, by the 110.3-metre (362 ft) telecommunications antenna on its roof. Including the antenna, the building stood at a total height of 527.3 metres (1,730 ft). The building's address was One World Trade Center, with the WTC complex having its own ZIP code of 10048 due to its large size.

The entire original World Trade Center was destroyed in the terrorist attacks of September 11, 2001; One World Trade Center was the first of the famous Twin Towers to be struck by a hijacked aircraft, at 8:46 a.m EDT, and the second tower to collapse, at 10:28 a.m. Of the 2,977 victims killed in the attacks, 1,402 were in or above the North Tower impact zone. The North Tower was replaced by the present-day One World Trade Center tower, which was opened in November 2014 as the lead building of the redeveloped World Trade Center site.
