What makes you think this is an exterior door? The flooring is the same.
Appears it is an interior door of an abandoned castle, based on the reply from Bagel5941
Most interior doors don’t have something that looks like what could be an apartment room number sign.
edit: but I suppose it could be an interior door, the sign isn’t clear enough to read
The sign says “the crooked room” and it was used to threaten naughty children with. Probably.
“I keep warning you. Doors and corners, kid. That’s where they get you…”
Not sure this is real but it’s the closest I could find to the origin of the image dated April 2nd, 2021.
in much more interesting news, today at work I got to explore an abandoned 500-year-old castle, seized by the state because of the owner’s massive tax evasion
So yes the place is 500yo, but it has been renovated 40 years ago, after being half destroyed during WWII. So it’s got ugly 80s decor vibes. And yes it’s called a château
