It has been recorded that the 13th floor of this world-renowned hotel is haunted by the ghosts of soldiers who were treated there during the WWII era. Unexplained noises and lights are seen here. Here is a history of the Biltmore Hotel: It served as a hotel in the early twenties, and then it was used as a hospital during WWII, where many people died. In 1968, they chose to turn it back into a hotel, and in 1983, they spent over 55 million to restore it.
