World Trade Center, New York City - aerial view (March 2001)

The original World Trade Center in March 2001. The tower on the left, with antenna spire, was 1 WTC. The tower on the right was 2 WTC. All seven buildings of the WTC complex are partially visible; refer to map below. The red granite-clad building left of the Twin Towers was the original 7 World Trade Center. In the background is the East River.

The World Trade Center (also known as the Twin Towers) are two former skyscrapers topping 527 meters (excluding the communication antenna).


They were constructed in 1968 (1WTC) and 1969 (2WTC), where the towers became the tallest skyscrapers in New York City City after their completion in 1970/71, respectively.

The south tower was known as 2WTC, and the north tower was known as 1WTC.

On September 11, 2001, two planes crashed into the towers at around 440 miles per hour (710 km/h) into the buildings, with the first hitting the 1WTC at 8:46 am, and the second hitting 1WTC at 9:03 am. 2WTC collapsed at 9:59 am, and 1WTC at 10:28 am.

Construction on the new complex and replacement, the One World Trade Center (dubbed Freedom Tower pre-2009) began in 2006, and completion in 2013.
