The sixth floor window of the Texas Book Depository building in Dallas is open slightly as it was 50 years ago for Lee Harvey Oswald.
A white ‘x’ on the street below the Texas Book Depository building marks the spot where JFK’s presidential limousine was when the fatal shots were fired. This marker has been placed on the street since the assassination. It is not an official commemoration by the city of Dallas. It just appears.
The building now houses The Sixth Floor Museum, which remembers the assassination. http://www.jfk.org/
