Find every Ruined Portal on your Minecraft seed — Java 26.3 & Bedrock 1.26.51, any seed, free, no sign-up.
Quick answer: Ruined Portals generate in every Overworld biome and throughout the Nether, each with a loot chest. They are among the closest structures to spawn: half of worlds have one within 300 blocks on Java and 300 on Bedrock. This finder marks both the Overworld and Nether portals at 99% accuracy on Java and 99% on Bedrock.
Ruined Portals generate in every Overworld biome — on the surface, underwater and underground — and throughout the Nether. They look like broken Nether-portal frames surrounded by netherrack, gold blocks and lava.
A few hundred blocks. Across 200 random worlds, half had a ruined portal within 300 blocks of spawn on Java and 9 in 10 had one within 400; on Bedrock the same figures are 300 and 400. Every 640 × 640-block area of the Overworld holds one, in any biome, so a world averages about 8 within 1,000 blocks of spawn. Many are buried or underwater, so dig around the marked point to find the chest.

| Half of worlds have one within | 300 blocks | 300 blocks |
| 9 worlds in 10 have one within | 400 blocks | 400 blocks |
| Worlds with one within 1,000 blocks | Every world tested | Every world tested |
| How many within 1,000 blocks, on average | About 8 | About 8 |
Measured with this finder on 200 random worlds in each edition, from the point where each world spawns you. Distances are rounded.
The loot chest is an excellent early-game source — it can hold obsidian (or even a full portal’s worth), flint and steel, gold, iron nuggets, fire charges and enchanted gear. Repair the frame with obsidian to make a working portal on the spot.
