Generation conditions
Minecraft divides the world into 34×34 chunk regions and picks one candidate position per region, keeping a separation of 12 chunks from the region edge. The candidate is then accepted only if the terrain at that position is suitable.
How to find a trial chamber
- Open your seed. Enter your world seed on the seed map and choose the Minecraft version your world was created in.
- Enable the layer. Turn on the trial chambers layer in the map panel.
- Pick the closest marker. Pan around spawn and choose the marker nearest to where you play.
- Copy the coordinates. Select the marker and copy its coordinates, or copy the ready-made teleport command.
- Travel there. Trial chambers generate underground across most overworld biomes. Tunnel to the marked coordinates around Y -20.
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.
