Saving the National Treasures
Every year, more than a million people visit the Rotunda at the National Archives in Washington, D.C., to gaze at three documents that define our nation's heritage: the Declaration of Independence, the Constitution, and the Bill of Rights. But these touchstones of democracy are in trouble. The ink is flaking from parchments that are already badly faded, while the glass casements built to exhibit them are disintegrating. To head off the danger, the Archives embarked on a five-year project to design state-of-the-art encasements and a new Rotunda.
Nova was given exclusive access to this project and follows the entire process from start to finish. Saving the National Treasures offers the colorful history of these documents and an insider's look at the engineering efforts that are safeguarding America's equivalent of the Crown Jewels.
