Bastion Remnant

Bastion remnants are the large, castle-like structures that are found in the Nether in all biomes except basalt deltas. Piglins will spawn here.

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

Structure
Bastion remnants generate 4 types of structures: bridges (with lava underneath), hoglin stable, housing units, and treasure rooms. Piglins and hoglins spawn frequently throughout.

These structures are the only place where the Pigstep music disc and netherite armor can be found naturally.

Treasure Room:
The treasure room contains a magma cube spawner, gold blocks, and various chests.

Trivia

 * Bastion Remnant is currently the only structure in Minecraft where double chests can generate and the only structure where they generate with loot in them.
