Korner's Folly

Built in 1880, Korner's Folly is genuinely one of the strangest houses in America — seven levels, 22 rooms with wildly different ceiling heights, and the oldest private theater in the country.

Korner's Folly, one of the strangest houses in America, was officially declared haunted after a 2009 paranormal investigation. The seven-level home with 22 rooms of varying ceiling heights and unusual angles seems designed to disorient the living -- and perhaps trap the dead. Most ghostly tales focus on the fourth floor, where investigators recorded voices from empty rooms, witnessed furniture moving on its own, and documented lights mysteriously flicking on and off. One investigator reported receiving three distinct taps on the head from an unseen hand. The Korner family lived in this eccentric home for generations, and some appear to have never left. Visitors have reported seeing figures in period dress moving through the oddly-shaped rooms, only to vanish around corners into impossible spaces. The temperature drops without warning in certain areas, and the sounds of children laughing have been heard in the private theater -- the oldest in America -- when it stands empty. The house's unusual architecture, with its tilted walls and angles that don't quite make sense, creates an unsettling atmosphere that paranormal investigators believe may trap spiritual energy.
