Free Stronghold Finder by Seed

Minecraft Stronghold Finder for any Seed

Enter a known Java 26.2 / 26.3 Seed and your current X/Z point to calculate the nearest Stronghold starting chunk. No account is required, and the Seed never leaves your browser.

Private: your Seed and coordinates stay in this browser, are not sent to MapMC, and shared links keep them after #.

The X/Z result is the Stronghold starting chunk used by Minecraft's locate system. It is not a Y level or the exact End Portal room.

How to use this tool

  1. 1

    Seed

    Enter your Java 26.2 / 26.3 Seed and current X/Z as the search origin.

  2. 2

    Find nearest Stronghold

    Calculate the nearest Stronghold. The returned X/Z marks its starting chunk, not the portal room or a Y height.

  3. 3

    Starting-chunk coordinates

    Travel to those coordinates in the matching world, then explore the Stronghold. Teleport only if commands and permissions allow it.

Minecraft Stronghold Finder FAQ

How does this Minecraft Stronghold Finder work?

It generates the 128 Stronghold starting positions for your Java 26.2 / 26.3 Seed inside a browser Worker and returns the position nearest to your X/Z origin.

Does the result point to the End Portal room?

No. It is the starting-chunk X/Z used by Minecraft's locate system. Explore the Stronghold to find the portal room and its Y level.

Does MapMC receive my Seed or coordinates?

No. Calculation happens in your browser, and shared state remains after the URL # symbol rather than being sent as a normal page request.

Does this Stronghold Finder support Bedrock Edition?

No. Results are verified for unmodified Minecraft Java 26.2 / 26.3 only, so they must not be used as Bedrock coordinates.
