From the Minecraft Wiki, summarised

How it generates

Bridges span open Nether terrain and lava seas, while corridors can be buried in netherrack.

Biomes

  • Nether Wastes
  • Soul Sand Valley
  • Crimson Forest
  • Warped Forest
  • Basalt Deltas

In Java, fortresses share a placement grid (minecraft:nether_complexes) with bastion remnants. Each 432×432-block region gets one candidate, which becomes a fortress or a bastion at 2:3 odds. A bastion that would start in basalt deltas becomes a fortress instead. Bedrock uses 480×480-block regions and picks a fortress 1 time in 3. Height limits aren't confirmed. Bedrock's added version is the Pocket Edition release.
