Norwich State Hospital was a hospital treating psychatric and criminal patients. It opened in October 1905. The population of the hospital peaked in the mid-1950s, when it had almost 3,000 patients. There are over thirty buildings on the property in various states of disrepair. Many of the main buildings are connected with tunnels. Some of these tunnels have since been filled in, but many still exist.
Norwich State Hospital closed entirely in 1996. The extensive tunnel network, full of cancer causing asbestos, along with the rotting underground tanks and old hospital landfills create very expensive cleanup costs. This, along with various state and town legislative issues, have left the property in limbo since its closure.
The location has been reported by staff and other witnesses to be haunted. Syfy Channel’s Ghost Hunters paranormal investigating team explored the location in their sixth season finale which aired May 5, 2010.
