Location: Howell, Michigan, USA
Operation Time: ? – 2004
Type: Not Kirkbride Plan
Status: Mostly demolished
The remains of the Hillcrest Sanitarium (possibly Sanatorium) lie several miles outside the Howell city limits. The building was originally used as an insane asylum, but it became a tuberculosis hospital in its later years. There have been many sightings of ghost children on site.
Now, the hospital ands its tunnels have been torn down, but a few of its buildings remain. Mysterious lights and noises have occurred on the site even after the demolition of the place. Homes are currently being built on where the tunnels used to be, and it is assumed that the houses will be haunted by the spirits who used to inhabit the hospital.
