New York City has a new tallest building - One World Trade Centre is now 1,271ft (387m) tall - just taller than the top of the Empire State building.
The huge construction, now 100 floors high, was built to replace the iconic twin towers that were destroyed in the 9/11 attacks.
The One World Trade Centre rises over the Manhattan skyline
In the coming months, the last four floors will be completed, making it the same height as the original One World Trade Centre north tower.
Next year the building will reach its full height.
Workers will add an antenna, which, if counted as part of the height of the tower, will make it the tallest in the US, and the third tallest in the world.
Vice Chairman of the Port Authority Scott Rechler said: "One World Trade Centre (WTC) is much more than an iconic symbol for New York ... it is a symbol of liberty and pride.
"It is perhaps the most complex construction job in our history ... it has been an act of passion and an act of patriotic duty.
He described the redevelopment of the entire Ground Zero site as a "game changer" for lower Manhattan.
Officials are building a transit hub and a performing arts centre alongside the numerous sky scrapers that are taking shape around the central memorial.
They hope that it will generate billions of dollars in economic activity for the city of New York.
One WTC, which will mainly be for commercial use, is due to open in early 2014.
I do plan on visiting New York hopefully sometime this year and witnessing the work done myself.
