Polish artist Daniel Czapiewski built the upside-down house to describe the times of the Communist era as well as the times we live in today.
No, the house did not fall from the sky. It was built that way.
One had better take a picture of the house now because who knows how long it will be there. Work of art or not, its foundations are suspended in the air.
The real question is - where is the cellar?
The house was not only built upside down, it is also slanted!
