Upside Down Homes and Buildings

Poland's got an upside down house.

 Calgary has an upside down church (used to be in Vancouver).

There's one in South Korea.

And Palma Nova has one called Katmandu.

There's an upside down White House in Pigeon Forge, Tennessee, and one in Orlando too (thx raevenfeather).

And, of course, there's also one in Japan.
