One World Trade Center

One World Trade Center, also known as the Freedom Tower, was constructed over approximately eight years, with its cornerstone laid on July 4, 2004, and completion in 2013.

The project faced delays due to disputes over funding, security, and design, leading to a construction period from 2006 to 2013.

The total construction cost was approximately $3.8 billion, making it one of the most expensive buildings globally at that time.
