The Griggs Mansion, 476 Summit Avenue in St. Paul, Minnesota, is currently on the market. This mansion is considered by many investigators to be the most haunted house in Minnesota. The building was used as an art school from 1939 to 1964 and was once owned by Carl Weschke of Llewellyn Publishing, who I suspect purchased it because of its spooky reputation.
While a lot of "supernatural activity" seems to be centered around the 4th floor, many parts of the house have been visited by entities as well. Six or seven entities have been felt, heard, made their existence known by various means and have actually been seen throughout the years. The mansion's spiritual occupants are a young maid, a gardener, a child apparition, a thin man in a black suit, a teenager, Amy, and a Civil War general, perhaps Chauncey Griggs himself. The 7th sighting could've been any of the male apparitions, because only the head of an unclear, male apparition appeared.
In addition to the apparitions all sorts of paranormal activity apparently goes on in the house.
Many unexplained, but typical incidents common in haunted houses have been reported, though no specific entity has been found to be responsible for the noises, annoying behavior that makes the living uncomfortable or befuddled. Windows that had been firmly closed, even nailed shut, have been found open in the morning. Footfalls have been heard traveling up and down the staircases. Shadowy presences have been seen. Unsuspecting students who rented the apartments, have been shaken awake, to find an undistinguished apparition head floating above their beds. Doors open and close by themselves. "Rasping coughs" have been heard coming from empty rooms. Light bulbs suddenly shatter, paper bags have been known to jump off the shelves, and jump across the floor. People in the mansion have felt presences walk by them. Some of the presences happen to appreciate art. While working in the art studio room, with the skylight on the top floor, students had felt presences peering over their shoulder to get a good look at their drawings in progress, perhaps studying with interest the student's efforts.
Unfortunately for me, the old movie trope of being able to buy an amazing house incredibly cheaply because of paranormal activity doesn't happen in the real world. The asking price for the place is 1.8 million dollars, well outside my housing budget. Here's the real estate listing - check it out while it's still available and take a look at the interior photos. The place is just beautiful, and for me ghosts would be a real bonus. The area even has some personal significance - my wife and I were married at 490 Summit, right next door.
I guess I need to work harder on those lottery spells...
