One World Trade Centre, Lower Manhattan, New York City, New York, United States

A report in September 2013 revealed that, at the time of the report, the World Trade Center Association (WTCA) continued to negotiate with the One World Trade Center in regard to the title "World Trade Center", as the WTCA purchased the rights to the name in 1986. The WTCA sought free office space in the tower worth US$500,000 in exchange for the use of "World Trade Center" on the One World Trade Center tower and associated souvenirs.
In May 2011, detailed floor plans of the tower were displayed on New York City's Department of Finance website, resulting in an uproar from the media and citizens of the surrounding area, who warned that the plans could potentially be used for a future terrorist attack. In April 2012, with the tower's structure nearing completion, the owners of 1 WTC began a public marketing campaign for the building, seeking to draw in visitors and additional tenants.
On November 12, 2013, the Height Committee of the Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) made the controversial announcement that One World Trade Center was the tallest building in the United States at 1,776 feet, declaring that the mast on top of the building is a spire since it is a permanent part of the building's architecture.
