How to use it
- Type /seed in game and copy the number into the seed box (text seeds work too).
- Pick the Java version your world was created in.
- Enter your current X and Z to sort the ocean monuments by distance from you.
- Copy the /tp command, or open the spot on the seed map to see the biomes around it.
How it works
The finder recreates Minecraft's own structure placement from the seed in your browser, using the open-source cubiomes library compiled to WebAssembly. For each area where a ocean monument can start, it works out the exact start point, then checks the biome there the same way the game does. Deep ocean biomes (including the warm, lukewarm, cold and frozen deep variants). They try to spawn once in every 32 × 32 chunk area, at least 5 chunks apart. Nothing is uploaded: the seed stays on your device.
Questions
How do I find a ocean monument without the seed?
Explore the biomes where they spawn: deep ocean biomes (including the warm, lukewarm, cold and frozen deep variants). On servers where you can't use /seed, ask an admin, or look for a seed shown on the server's website.
Does this work on Bedrock Edition?
Not for structures. Bedrock shares Java's biome generation since 1.18, but it places structures with different rules, so these coordinates only match Java worlds.
Is using a finder cheating?
It reads the same information the game uses to build your world. In single player it's up to you; on servers, check the rules, because some ban seed tools.
What will I find in a ocean monument?
Eight gold blocks hidden in the treasure room, prismarine, sponges, and the Tide armour trim from elder guardians.
How do I breathe in an ocean monument?
Bring Potions of Water Breathing and a helmet with Respiration, or a conduit. Elder guardians also give Mining Fatigue, so bring milk or plan for slow mining.
