Ruined portals in numbers

Measured with our engine on 10 test seeds, Java 1.21.1, in an area of 8,192 × 8,192 blocks around 0, 0 for each seed.

What is a ruined portal?

A ruined portal is a broken Nether portal frame with a loot chest beside it. Players look for one to get obsidian for a portal and gold gear. 5 things to look for inside:

Watch out: Lava and magma blocks are part of the structure. The Nether version is built from blackstone with chains.

Where ruined portals generate

Ruined portals generate in almost every Overworld biome and in every Nether biome; they are the only structure in more than one dimension. In the Overworld they can be on the surface, underground, on the ocean floor, half-buried in deserts or inside mountains. In the Nether they generate between Y 27 and Y 100.

This is how the ruined portals in our test areas split between biomes in the Overworld:

BiomeShare of ruined portals
Forest11.4%
Plains9.6%
Ocean7.6%
Savanna5.5%
River5.5%
Lukewarm ocean5.3%
Desert4.1%
Deep lukewarm ocean3.5%
All other biomes47.5%

Measured with our engine on 10 test seeds, Java 1.21.1, in an area of 8,192 × 8,192 blocks around 0, 0 for each seed. Biome taken at the centre of each start chunk, at Y 64.

In the Nether, ruined portals split between biomes like this. Pick Nether under Dimension to see them on the map.

How far apart ruined portals are

The game splits the Overworld into square regions of 40 × 40 chunks (640 × 640 blocks) and makes one attempt in each. Our test areas held about 164 regions each and between 158 and 163 ruined portals, so about 98% of regions got one.

Engine results for the 10 test seeds, Java 1.21.1. Placement: 1 per 40 × 40 chunks.

The median is a typical seed. Yours can be much closer or further, which is why the finder lists results for your exact seed.

Tips for finding and exploring ruined portals

How to use the coordinates in game

  1. Press F3 to see your own X and Z, then head towards the result’s X and Z. Ruined portals are at the surface in most cases, but some are underground or underwater.
  2. With cheats on, tap a marker or Copy and run /tp @s X ~ Z; the ~ keeps your current height.
  3. The coordinates are the north-west corner of the chunk the ruined portal starts in, the same chunk /locate structure #minecraft:ruined_portal points to.

Set “Search near” to your base or the map centre to list ruined portals around a different spot. To see ruined portals next to every other structure type, use the structure finder.

How accurate the ruined portal finder is

We started a real Java 1.21.1 server for 10 test seeds. Our nearest ruined portal to 0, 0 matched the game’s /locate on 10 of 10 seeds, and the game confirmed 50 of the 50 ruined portals we listed. Other versions haven’t been checked against the game yet.

Bedrock Edition: Java only for now

On Bedrock, every ruined portal has a chest, and each obsidian block has a 20% chance to be crying obsidian (15% on Java). A Java map would point you to the wrong places, so the finder doesn’t show Bedrock results yet.

Frequently asked questions

How do I find a ruined portal in Minecraft?

Enter your world seed above, pick the Java version the world was created in, and the finder lists the nearest ruined portals with exact X and Z coordinates. A Nether portal needs at least 10 obsidian (a 4 × 5 frame without corners). Crying obsidian in the frame stops the portal from lighting.

What Y-level are ruined portals at?

Ruined portals are at the surface in most cases, but some are underground or underwater.

How far away is the nearest ruined portal?

On our 10 test seeds the nearest ruined portal to 0, 0 was 286 blocks away for a typical seed, ranging from 25 to 446 blocks. Your seed can be closer or further, so check the list for your own world.

Does the ruined portal finder work on Bedrock Edition?

Not yet. On Bedrock, every ruined portal has a chest, and each obsidian block has a 20% chance to be crying obsidian (15% on Java). The finder only shows Java results, so it never points you to the wrong place.

How accurate is the ruined portal finder?

We checked it against a real Java 1.21.1 server: the game confirmed 50 of the 50 ruined portals we listed, and our nearest result matched /locate on 10 of 10 seeds.

How do I find my Minecraft seed?

In Java Edition, type /seed in chat. It works in single player even with cheats off; on a server you need operator rights. Text seeds work too: paste them as they are.
