Nether Fortress/Structure

A Nether Fortress is a structure generated in the Nether. This is a tutorial regarding how to build Nether Fortresses.

Building a Nether Fortress
In the following blueprints, "Layer 0" means that this is level with the path(s) that connect them. Negative numbers indicate that they are below the path. The bottom-most layer is copied all the way to the surface.

Bridge Closed Intersections
These intersections connect four bridges and are somewhat closed-in.

Bridge Open Intersection
These intersections connect four bridges.

Blaze Spawner
The entrance is on the bottom side of the blueprints. They can connect to a bridge or a corridor.

Bridge Staircases
The stair case goes to the right and the exit is to the left at the top. These connect to bridges on the top and bottom. These can be mirrored to turn the other direction.

Lava Well Room
These are used to connect bridges and corridors. On Layer 4, the three fences above the path show the bridge side.

Nether Wart Farm
Layer 9 is split in two because there is a possibility of an exit going up the stairs. These connect to three corridors.

Straight Corridor
These are made in 5x5 segments.

The Curved Corridor
These connect to corridors. This blueprint shows a left turn, but it can be mirrored to make a right turn. The chest is optional.
