Nether Fortress Finder
Nether fortresses are where blaze rods and wither skeleton skulls come from. This finder opens the map in the Nether with every fortress for your seed marked and the five nearest listed.

Positions are for Java Edition. Bedrock Edition places structures differently; they will be added to the Bedrock map once they match the official Bedrock server.
How to use it
- 1
Enter your seed
Type or paste your world's seed in the Seed box and pick the version you play. In Java Edition, type /seed in chat to see it. If you upgraded an old world, pick the version its chunks were generated in: chunks that already exist keep what they had.
- 2
See the nearest
The Find tab lists the five nearest fortresses to the middle of the map, with coordinates. Drag the map somewhere else and press Find to search from there.

Go there
Click a marker or a result to copy its coordinates or a /tp command, then paste it in the game.
Fortress or bastion
Since Java 1.16 the Nether holds one large structure per region of 27 by 27 chunks. Roughly 2 in 5 of them are nether fortresses and the rest are bastion remnants. Bastions cannot generate in basalt deltas; from Java 1.18 a spot there becomes a fortress instead.
Getting there from the Overworld
One block in the Nether is eight in the Overworld. To reach a fortress at Nether X, Z through a new portal, build it in the Overworld near 8 × X, 8 × Z. Or walk there in the Nether from the portal you have.
Checked against the game
We compared the map with the official Minecraft Java server's /locate on 20 held-out seeds: 120 of 120 answers for this structure were the same chunk (Java 26.3 and 1.21.4). How we tested
