Today of 50 years ago was the day when President Dallas has been assassinated by Lee Harvey Oswald (or, that is said by official papers).
That is a screenshot taken by Google Maps of that place today, 50 years later.
The building on the left (the brown one) is the Texas School Book Depository. From the 6th floor Oswald shot to Kennedy. Today here is a museum known as “The Sixth Floor Museum“.
