The Skyscraper Museum was displaced from its temporary gallery in Lower Manhattan on 9/11. As a result, we wondered how to find a way to respond to the crisis and questions of a story so central to our institution's identity. WTC: Monument was presented in the galleries of The New-York Historical Society from February 5th through May 5th, 2002. We are extremely grateful to President Kenneth T. Jackson for offering us their galleries for that purpose. In addition, the Society's trove of treasures and the generous assistance of its staff greatly enriched the exhibit.
