How the nether fortress finder works

Nether fortresses are where blaze rods and wither skeleton skulls come from, so every playthrough needs one. This finder switches the map to the Nether and lists the fortresses closest to where your Overworld spawn portal would land, which is your spawn coordinates divided by eight.

Enter a seed in the box above the map and press Map it. The Find nearest panel on the left runs automatically for this structure and lists the closest results with distances from spawn. Click a result to center the map on it, then use Copy X Z or Copy /tp. Change the version selector to match your game; placement shifts between updates.

Tips

• Nether coordinates are one eighth of Overworld coordinates. The map handles the conversion when you switch dimensions.
• Fortresses and bastions share the same region grid; where one generates the other does not.
• The blaze spawners sit on the fortress’s exposed walkways, not at the marker’s exact block.

For what to expect inside, what spawns there and how to loot it safely, read the wiki’s nether fortress guide. To see every structure type at once, open the full seed map.
