The National Archives building is located on Pennsylvania Ave. in Washington D.C

 The building was constructed between 1931-1933, during the term of President Herbert Hoover

 The Declaration of Independence was put on display in the National Archives in 1952

 When the building closes, the documents kept in the Archives are stored in a vault below the building's main floor

 The Declaration of Independence, the Constitution, and the Bill of Rights are protected by their own glass and bronze cases, where helium protects the document, rather than harmful air

 There are two portraits in the rotunda of the building which depict the presentation of the Declaration of Independence to the Continental Congress and the presentation of the Declaration of Independence to George Washington

  On the outside architecture of the actual building, there are many statues.  Under one statue reads the phrase, "What is past is prologue", a famous quote from Shakespeare

  Inside the building, photography is prohibited, due to the effect the flash has on the documents.  This rule was made official in 2010

 There are many items stored in the multiple locations of the Archives, such as Boston and San Francisco
