Centennial Hall, Valentine’s Historical landmark built in 1897 and now the oldest standing high school building in the state of Nebraska, houses a heritage museum of area historical artifacts. The ornate style of architecture reveals the past and will likely never be revived in today’s structures as the cost of the fine craftsmanship in construction would be prohibitive.

The museum has twelve rooms, each with a different theme, including the Hallock Bell collection with over 1,700 bells, the Days of Yesteryear room, the Military room, and many more.

The building is also rumored to be haunted and has been the site of several paranormal investigations. Occasionally, a vacant rocking chair or the sound of music when there is none testify to a ghostly presence.
