By 1983, the World Trade Center complex, including the Twin Towers, was already fully constructed and operational. The iconic towers, designed by architect Minoru Yamasaki, were completed in 1973.

The construction process began in 1966 and involved significant engineering innovations, including a “tube-frame” structural design that made the buildings lightweight but strong. | History In Pictures
