World Trade Center spire installed

Steelworkers have completed installation of the One World Trade Center’s spire, bringing its height to 1,776ft (541m).

Steel workers have completed installation of the spire for One World Trade Center in Manhattan, bringing its height to 541m.

Installation of the 1,383t spire finished on 11 May. It was split into 16 parts to form the four lower rings and a further 18 parts to create the spire itself.     

The tower is now the tallest in the western hemisphere, beating London’s shard at 308m.

Construction of the building is due to be completed in 2014. It is the tallest of five skyscrapers being built on the site of the twin towers, destroyed in 2001.

The height [1,776 feet] reflects the year the year Americas’s Declaration of Independence was signed. The site will also include a 9/11 memorial.
