An inspiring and intimate story of the birth and growth of an American symbol.

For a time, its towers were the tallest buildings on earth, and The World Trade Center -- an engineering marvel -- came to symbolize American prosperity and strength. Recalling a more innocent era, World Trade Center: In Memoriam was filmed just months before the towers' tragic demise and subsequently enriched with heartfelt reflection from host Harry Smith.

This new production from The History Channel charts the history of the towers' construction, revealing the controversies, decisions and innovations that surrounded the project, and -- through interviews with those who proudly and ambitiously dreamt, designed and built the complex --examines the monument as both architectural achievement and cultural icon. What emerges is not only a tribute to a building, but an inspiring and intimate story of the birth and growth of an American symbol.

Filled with extraordinary photos and archival footage of the construction of America's beloved twin towers, this is a comprehensive and unforgettable celebration of a vanished landmark.
