The Sixth Floor Museum at Dealey Plaza

The Sixth Floor Museum at Dealey Plaza is a museum located on the sixth floor of the Dallas County Administration Building, formerly the Texas School Book Depository, in downtown Dallas, Texas, overlooking Dealey Plaza at the intersection of Elm and Houston Streets. The museum examines the life, times, death, and legacy of United States President John F. Kennedy, and the life of Lee Harvey Oswald, as well as the various conspiracy theories surrounding the assassination.

The museum's exhibition area uses historic films, photographs, artifacts, and interpretive displays to document the events of the assassination, the reports by government investigations that followed, and the historical legacy of the tragedy. The museum is self-sufficient in funding, relying solely on donations and ticket sales. It rents the space from the County of Dallas.
