Stonehenge

During the early 20th century, restoration work was done on Stonehenge to right some toppled and leaning components of the monument; however, the majority of the structure's elements had survived from prehistoric times to the modern era intact.

But in "The Black Knight" we are presented with a large-scale action scene in which a troupe of knights and soldiers use horse teams, blocks-and-tackle, and whatever other means they can round up to totally demolish Stonehenge! Afterwards, the movie never returns to the issue, and no explanation of how this Wonder of the Ancient World was restored is offered. The audience is left to assume that a group of more responsible, historic-preservation-minded knights plundered their peasantry for funding and reconstructed Stonehenge for posterity.
