Landing on the Melbourne Citadel in Microsoft Flight Simulator: the backstory on this is someone mistakenly entered “212” into OpenStreetMap instead of “2” for the number of stories that a building in Melbourne, Australia had. Apparently, the information in OSM is used to generate maps and landmarks in Microsoft Flight Simulator, which just released a new version, and the monstrosity in this video was the result.
[UPDATE (8/21/2020): And the Washington Monument looks less accurate. Found an article with more examples.]
