how much money did the twin towers cost
World Trade Center (1973–2001) The core of the complex was built between 1975 and 1985, with a cost of $400 million (equivalent to $1.86 billion in 2016).[6] The World Trade Center experienced a fire on February 13, 1975,[7] a bombing on February 26, 1993,[8] and a bank robbery on January 14, 1998.[9] In 1998, the Port Authority decided to privatize the World Trade Center, leasing the buildings to a private company to manage, and awarded the lease to Silverstein Properties in July 2001.[10]
