Works in Java versions 1.12+
Swamp is the only biome type that doesn't quite touch the coast but it makes up for it by having a [double witch hut](https://imgur.com/a/eOVhHYr)
A taiga village that ends up bleeding into a mega taiga biome, in a sort of crater. To the bottom right you can see the cave entrance, which leads into a very spacious cave, a church has been demolished to let you see it as it is otherwise floating over the entrance.

Video of time-lapse with good music: https://youtu.be/rT5e0yMaSKk
This video is copyrighted (hopefully not blocked in "some countries") but the music fits so well with the replay mod time lapse. It took an half hour real time for the whole thing to burn down.
Note: For whatever reason, the same seed on the same version can have different structure generation (IDK why). So it is the variant that has the ruined portal frame inside the mansion that works.
