One of the most well known places in America is apparently a very haunted one too.  The White House is at 1600 Pennsylvania Avenue in Washington, D.C. Several former presidents (dead of course) have been seen here walking around in ghostly form including President Lincoln (frequent sightings), Harrison, Madison and Jackson.   It is believed that a phantom black cat haunts the basement of the White House as well, and appears in moments where the United States stands still and mourns. The black cat has made its presence known just before John F Kennedy was killed, right before the stock market crash of the 1920s took place, and on many other different occasions throughout history.
