I was searching a random world I made and I found a stronghold that contains only the stairwell, some other room, and then the end portal as you can see in the photos. I thought this was pretty neat and said wow it's not like there's anything above me or anything.
There is a massive trial chamber above the stronghold. Not only that but there is a giant supermassive mineshaft next to the trial chamber. If that wasn't enough the mineshaft generated inside the trial chamber a little bit, you can see a chest in a minecart inside the trial chamber in one photo.
I also found a 37 block tall pillager outpost in a lukewarm ocean and warm ocean that has a coral reef next to it all in shallow water (the pillager outpost is only 16 blocks in the water) in the same world, I've included a screenshot of that.
The seed is: -5891887669115679460
Cords for the mineshaft are -82092 ~ -65147
Cords for the pillager outpost are: -19744 ~ -18955
Has anyone seen a stronghold like that? Those are the only parts of it.
