That’s not a ghost in our homepage picture; it’s just a statue (at least, we think it is). But it’s easy to imagine ghosts wandering the vast gardens here at the Palace of Versailles, about 12 miles outside of Paris. One ghost in particular has a reputation for showing herself. In 1901, on a sultry August afternoon, two visitors to the Gardens of Versailles claimed to have witnessed the gardens magically transform to their 18-century grandeur. Then, they said, they encountered the ghost of Marie Antoinette, whom they spotted calmly lounging and drawing in her sketchbook. The queen of course had been guillotined a century earlier. The story was later adapted as an opera, which debuted in 1991.
