The SK Pierce Mansion, located in Gardner, Massachusetts, was built in 1875. The owner of the property was Sylvester Pierce, who made his money from the company he founded, the S.K. Pierce & Sons Furniture Company. The Victorian mansion measures 6,661 square feet, and it is known both locally and nationally for being “haunted.”

Even though the house hasn’t sold, there is no denying its visitor appeal. It has a 4.8/5-star review on Facebook from adventurers hoping to catch a glimpse of the paranormal (or, at least, to see a cool-looking house). The ghost adventurer community would no doubt be bummed out if the SK Pierce Mansion did sell and forever close off to the public.
