This seed is the first one I’ve come across which have for unknown reasons generated a stronghold underwater. Another cool feature of the seed is that the stronghold is located just next to an ocean monument. The chance for this happening is obviously extremely small and that makes it a very unique and rare seed.

How to find the underwater structures?
When creating the world make sure to enable cheats since this is necessary for navigating in the world. Type the following text command once you’ve spawned to get the coordinates for the stronghold and ocean monument: /locate stronghold. Then type the following command to teleport to the location: /tp @a -912 32 -1216
You will spawn on the bottom of the ocean at a huge stronghold which for some reason has been generated underwater. Next to the stronghold there is also an ocean monument.
The stronghold is quite bugged. There are multiple openings all over the stronghold which connects directly to the water, but for some reason it’s not flooded.
