Bastion Remnant

Bastion remnants are large, castle-like generated structures found in the Nether in all biomes except basalt deltas. Piglins spawn in this structure on generation. Hoglins may also spawn on generation in bastion remnants if a hoglin stable generates. Additionally, a magma cube spawner generates in treasure rooms. They are guarded by piglin brutes. Bastion remnants are the only way to obtain the Pigstep music disc and the snout banner pattern.

Generation
Bastion remnants can be found in all of the biomes in the Nether except Basalt Deltas. They can even be found in the Soul Sand Valley even though Piglins are scared of soul fire and its related items.

Piglins, piglin brutes, and hoglins that spawn on generation in bastion remnants do not despawn naturally, nor do they hunt each other. Piglin brutes also spawn exclusively here one-time initially, and do not despawn unless killed.

Structure
Bastion remnants generate as 4 types of structures: bridges, hoglin stables, housing units, and treasure rooms. Each type has its own set of structures that compose it. These structures may be supported by ramparts that contain cave-like paths. Piglins, piglin brutes, and hoglins spawn frequently throughout.

All bastion remnant structures found below are located in the folder client.jar/data/minecraft/structures/bastion.

Bridge
The bridge consists of a large ruined rampart structure with a piglin face carved into it. The inside of the "mouth" consists of multiple levels of walkways surrounded by lava. A damaged bridge goes out from the mouth, with a support pillar on the far side.

Hoglin stables
The hoglin stables consist of a three-part rampart with damaged hoglin stables on either side. Hoglin stables' pieces are contained in the subfolder hoglin_stable.

Housing units
The housing unit consists of multiple ruined two-part ramparts arranged around a central courtyard with nether wart growing in the middle. Housing unit pieces are contained in the subfolder units.

Treasure room
The treasure room structure consists of a large rampart supported by buttresses, with a bridge going between it and the treasure room itself. The treasure room consists of many bridges suspended above a lava floor. At the bottom of a treasure room, there is a magma cube spawner, and a center loot area consisting of blocks of gold, as well as 1 or 2 treasure chests. Additional chests generate in the bastion, but they use the "generic" loot table instead of the "treasure" loot table. Treasure room pieces are contained in the subfolder treasure.

Bridge
This loot appears in some structures in bridge bastion remnants.

Generic
This loot appears in chests throughout all types of bastion remnants.

Hoglin Stable

Treasure
This loot appears in some structures in treasure bastion remnants.

Trivia

 * Before Beta 1.16.0.59, some bastion remnant loot tables $5/6$ contain entries for spectral arrows, despite them not existing in that version of the game.
 * This was likely not an error from copying the loot tables $1/6$, as both editions had different loot at the time.
 * The structure, despite containing the word "mirrored", it is not stored as mirrored like the other mirrored stairs. This has no effect on generation due to the placement of jigsaw blocks in the structure.
 * $1/3$, before 1.16 pre-3, there were multiple unused structure files.
 * Two large stables were unused:.
 * Three sets of stairs were unused: . They are removed as of 1.16 pre-release 3.
 * $$, there are multiple unused structure files. Unlike the unused structures $$, these structures are more technical.
 * Two files named contain blocks that have not been added to the game, including.
 * A test structure file,, contains two oak signs, some jigsaw blocks, stained glass, and stone.
 * Buried sections can exist within the bastion and alongside it. Ore may generate in netherrack alongside or within it, but glowstone blobs can do so within its air.
