A 12700-ton church was moved ~850m in 70s Czechoslovakia to make space for coal mining [0][1]. It wasn't in use during the move though. :)
The rest of the town was demolished, and a new one (with same name) was built nearby. Mining has stopped since and there's a giant lake in the old town's area now.
There are several videos about the event, but most of them with Czech commentary only… Still, it's interesting to at least skip around the video [2].
