The Winchester House

One of the strangest structures in the United States is the home of the late Sarah Winchester. The widow of gun magnate William Winchester, Sarah believed the ghosts created by her husband's Winchester rifles would come for vengeance. To protect her, she built a mansion in Northern California that was endlessly under construction for 36 years. It is said she believed that keeping it always in flux would ward off spirits who'd do her harm. But the construction is nonsensical at best. There are windows that look into other portions of the home rather than outside. There are doors and stairwells that lead nowhere. All told an estimated $75 million dollars by today's rates was spent on the house, which has been a tourist attraction since 1923, five months after she died of a heart failure at 83.
