Built in 1929, the Molly Stark Sanatorium in Stark County, Ohio, operated as a tuberculosis hospital for decades before its closure in 1976. Now a decaying landmark within Molly Stark Park, it’s rumored to be haunted by the spirits of former patients—urban explorers and ghost hunters have reported unexplained voices, shadow figures and cold spots. The sanatorium Spanish Revival architecture is still striking, but the building is closed to the public due to safety concerns. Despite its closure, it remains a popular subject on paranormal forums and is occasionally featured in local news and ghost tour circuits.
