A lava well room in a Nether Fortress
Nether Fortress are rather large Structures found in the Nether. They generate partially underground.
The exterior appearance of the Nether Fortress are made out of Nether Bricks forming giant walkways on top of high pillars. There are also rooftop areas with Blaze Monster Spawners. Parts of the rooftop is fenced in by Nether Brick Fences. The Fences are also used as windows and decorative elements in the outer walls of the Nether Fortress.
Inside the Fortresses there are various rooms interconnected through corridors:
- Lava well rooms(one per fortres)
- Rooms with Nether Brick Stairs in the center, and Soul Sand at the sides of the stairway containing two 2×5 rows of Nether Wart growing on it.
- Rooms with four exits. Some of them lead only to the outside.
- Rooms in the pillars with a simple stairway of Nether Brick placed against a wall, leading up to the floor above.
- Open or closed walkways between the different parts of the Fortress. These are called Nether Bridges, and can contain Chests with various loot.
In a Chest found at a Nether Bridge the Player may find:
|Group count: 2-4|
|Flint and Steel||5/73||6.8%||1|
|Gold Horse Armor||8/73||11.0%||1|
|Iron Horse Armor||5/73||6.8%||1|
|Diamond Horse Armor||3/73||4.1%||1|
- Some Nether Fortresses have no growing room, so the Player won't find any Nether Wart in them.
- Nether Fortresses are the only places where Blazes and Wither Skeletons naturally spawn. Zombie Pigmen, Magma Cubes, and Skeletons can also spawn here.
- Nether Fortresses are one of the biggest Generated Structures, along with Strongholds and Abandoned Mineshafts.
- Nether Fortresses are considered dangerous as Blazes and Wither Skeletons are known to spawn inside.
- Chests only spawn in Nether Fortresses if the world was first generated after Update 0.12.1.
