Generation conditions

Minecraft divides the world into 20×20 chunk regions and picks one candidate position per region, keeping a separation of 8 chunks from the region edge. The candidate is then accepted only if the biome at that position is suitable.

How to find a ocean ruin

  1. Open your seed. Enter your world seed on the seed map and choose the Minecraft version your world was created in.
  2. Enable the layer. Turn on the ocean ruins layer in the map panel.
  3. Pick the closest marker. Pan around spawn and choose the marker nearest to where you play.
  4. Copy the coordinates. Select the marker and copy its coordinates, or copy the ready-made teleport command.
  5. Travel there. Ocean ruins are the fastest route to a treasure map. Look for candidates in shallow ocean close to a beach.

Coordinate notes

Markers are placed at the structure start position — the corner chunk Minecraft uses to begin generation — offset to the centre of that chunk. The building itself extends outward from there, so expect the visible structure to sit within a chunk or two of the marker.
