Centennial Hall has stood since 1897, and has apparently aquired a ghost or two.
Valentine, Nebraska
3rd and Macomb Streets, Valentine, Nebraska 69201
Centennial Hall was originally built in 1897 and used as the school in Valentine, it is now listed as a historical marker (Nebraska's oldest standing school.)
According to folks around town, you could hear music coming from inside, though the building was empty. During an investigation of the building multiple photos were taken with "orbs" visible. Also, video tape evidence showed a rocking chair (barely) rocking on what seemed to be it's own power. Most interestingly, an EVP was recorded. All males were in the building - though a female voice can faintly be heard.
The haunting is supposedly a girl named Lila who died after becoming ill at the school in 1943.
Be aware that the building is now a museum and open to the public during the summer. The building is closed to the public at all other times.
Our thanks to Zach Dean for alerting us to this haunting!
