The man was killed there in 1783. Killer never found. Lights flicker although there is no electricity, ghosts seen on roof and tower, film appears on vehicle and will not come off until you are within a couple miles of the building.
Voices call out names of murdered children, etc, etc.
Next day, Rock was moved, guy was gone. Imprint of Devil's Footprint and Man's footprints. Try to chisel it away but it returns. Legend has it that there are two sisters who have tomb stones there but are not buried there because their bodies were never found. They believe the girls might have died in an old well or mine shaft.
