Andrew Bayne Memorial Library in Bellevue Pittsburgh is haunted. It was built in 1875 as a three-story house and was given to the borough for use as a park and library by the owner (at the time), Amanda Bayne Balph. It was stated in her will that no trees should be taken down on the property but in 1998, it was necessary to remove one tree because of Dutch Elm disease. Unfortunately, this tree was 300 years old and was named the “Lone Sentinel” (it was recognized in 1983 as the largest American elm in the state). All of this tree business has a purpose…some believe that the removal of this tree increased the paranormal activity in the library (Amanda Bayne is apparently not happy with the removal of the tree).
Some accounts state that the ceiling fans and lights turn on and off on their own, computer screens show random numbers, there are moving shadows, and a woman in Victorian clothing has been seen. The library has appeared in Jeff Belanger’s book, “The World’s Most Haunted Places” (of which I own a copy surprise, surprise!).
