Manteno State Hospital was a psychiatric facility that closed in 1988 and has since become the subject of numerous paranormal claims. Reports of haunting often describe disembodied voices and the unexplained sounds of objects moving, particularly in the abandoned buildings. Guests and visitors have also claimed to see shadowy figures and experience a general feeling of being watched or followed within the former hospital grounds. Many accounts mention hearing unexplained sounds such as disembodied voices or whispers, and objects that appear to move on their own. Sightings of shadowy figures or unexplained shapes are frequently reported by visitors to the property. Many people report feeling uneasy, a sense of being watched, or the feeling of being followed while on the hospital grounds. As a psychiatric hospital that treated thousands of patients, Manteno is often associated with a history of difficult experiences, which contributes to its notoriety as a haunted location. The hospital closed its doors in 1988 after a long period of operation and is now largely abandoned. While the buildings were eventually demolished in the mid-1990s, the land is now mostly used for farming and the grounds are still visited by thrill-seekers and paranormal enthusiasts.
