Today, construction crews placed the final part of the spire on One World Trade Center.
The lower Manhattan building now measures a symbolic 1,776 feet — a patriotic reference to the year the Declaration of Independence was signed — making it the new tallest skyscraper in the Western Hemisphere.
The first part of the spire was lifted into place in December.
Onlookers watched as construction crews topped the building with the final part of the spire today.
