Dealey Plaza: Dallas, Texas
The Big D is well known for cowboys, J.R. Ewing and football, but it's also known for a tragic event in America's history: the assassination of President John F. Kennedy. Kennedy was shot while riding in a presidential motorcade through Dealey Plaza in 1963. Witnesses claimed to have seen a man in a window of the Texas School Book Depository, and police later discovered a sniper's nest and rifle on the sixth floor, leading them to the alleged shooter, Lee Harvey Oswald.
The depository became a symbol of hate, and many locals wanted it demolished. Instead, the sixth floor is now a museum dedicated to Kennedy and the events surrounding his assassination. Some areas of the sixth floor have been restored to their original appearance in 1963, and visitors can view more than 400 photos and artifacts that reconstruct the political scene of the early 1960s. The assassination is still the subject of many conspiracy theories, and millions of visitors travel to Dealey Plaza every year to remember Kennedy and get a glimpse of where his killer stood.
