Excuse me, what is the name of the most strange building in the world, with the door facing down, the window facing the wall and the stairs facing the other way?

It seems that it was built by an American arms dealer or inventor to stop curses or ghosts.

I can't find it.

Winchester Mystery House

Location: California, USA

Background: The owner and designer of Winchester mystery house is Sarah Winchester, the female boss of Winchester Rifle Company. It is said that this building originated from a mysterious story. William Winchester, the founder of Winchester Rifle Company, is Sarah's husband. With the bizarre death of her husband William and her daughter, superstitious Sarah listened to the astrologer. Astrologers told her that Winchester rifles caused many deaths, and her husband and daughter were cursed by these undead. She must build enough houses for the dead to live in in order to lift the curse, and the more bizarre the architectural style, the better. So Sarah designed and spent a lot of money to build a lot of strange houses. The construction of these buildings began in 1884 and continued until Sarah died in 1922.

Stranger: Sarah has never been a fan of architectural design. On the contrary, she prefers random design. As soon as she was inspired, she immediately added a note to the design, thus forming many shapeless rooms or strange building structures. The most famous buildings include 40 bedrooms, 3 elevators, 47 fireplaces, 17 chimneys and 467 doors. The building originally had seven floors, three of which were destroyed by the 1906 earthquake. Nowadays, visitors to the Mystery House can still see many strange structures, such as stairs leading directly to the roof.
