This [St. Paul, Minnesota] building, known as Griggs Mansion after its original owner, is one of the best preserved, as it still boasts wood-panelled walls and stained glass installed at the time it was built in 1883...
In 1915, a maid in the house apparently hanged herself on the fourth-floor landing, and ever since that area of the house has been subject to strange noises and scary premonitions.
The library is another area of the house where many visitors claim to have heard a bizarre rustling, which has been attributed to the house's gardener Charles Wade, who loved to flick through books there.

One particularly terrifying apparition is a white-haired man wearing a black suit and top hat, who has twice appeared to residents.
When a psychic medium was brought to the house, she claimed to sense the presence of a Civil War officer - thought to be the house's first owner, Chauncey Griggs.
In 1969, sceptical journalists from the St Paul Pioneer Press volunteered to spend a night in the house to research an article on the supernatural claims.
They stayed on the fourth floor, near to where the unfortunate maid had died half a century earlier - but by 4am, they had been driven out of the mansion by their terror.
There are lots of good photos in The Daily Mail article, but the details about the hauntings, which I've excerpted above, are rather sketchy. More details about the ghosts, including a child and a teenager, as well as some more photos of the place, are available at: Griggs Mansion - HauntedHouses.com.
