Newly updated, this is the one and only official companion book to the memorial plaza, created by the 9/11 Memorial Museum staff and originally published for its opening on the tenth anniversary of the World Trade Centre attack. In sombre words and chilling photographs - some never before published - the book tells the story of the World Trade Centre buildings; the earth-shaking attack; the aftermath, as anxious rescue efforts became months-long recovery; the public debate over how to commemorate those lost; the plans finally approved for a plaza and museum. This new edition contains a chapter dedicated to the remarkable nine-story underground 9/11 Memorial Museum, full of interactive exhibits that honour the meaning of 9/11 and the nation's response to the disaster. Illustrations and text come from the 9/11 Memorial Museum's collection, including its extensive oral history transcripts.
