Bastion Remnant

Bastion remnants are large, castle-like structures that are found in the Nether in all biomes except basalt deltas. Piglins spawns in this structure on generation. Hoglins may also spawn on generation in bastion remnants which contain hoglin stables, and a magma cube spawner generates in treasure rooms. Bastion remnants are the only way to obtain the Pigstep music disc and the snout banner pattern.

Generation
Bastion remnants are found in the following nether biomes:
 * Crimson Forest
 * Nether Wastes
 * Soul Sand Valley
 * Warped Forest

Piglins and hoglins that spawn in bastion remnants will not despawn naturally, nor will they hunt each other.

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 which contain cave-like paths. Piglins 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
A housing units consists of multiple ruined two-part ramparts arranged around a central courtyard with nether wart growing in the middle. Housing units pieces are contained in the subfolder units.

Treasure room
The 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 which consists of blocks of gold. One or two chests also generates with loots. Treasure room pieces are contained in the subfolder treasure.

Trivia

 * Prior to 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 very 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.
 * $1/3$, there are multiple unused structure files.
 * Two large stables are unused:.
 * Three sets of stairs are unused:.
 * $$, there are multiple unused structure files. Unlike the unused structures $$, 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.
