Find every Ocean Ruins on your Minecraft seed — Java 26.2 & Bedrock 1.26.30, any seed, free, no sign-up.
Quick answer: Ocean Ruins generate submerged across warm and cold ocean biomes in the Overworld, sometimes hiding buried-treasure maps. This finder marks them at 99% accuracy on Java and 98% on Bedrock.
Ocean Ruins generate on the sea floor in warm and cold ocean biomes in the Overworld, as scattered crumbled buildings. Warm-ocean ruins are built from sandstone, cold-ocean ruins from stone — and they often appear in small fields rather than alone.
Enter your seed and the finder marks every ruin field. Open a marker for coordinates and dive in — bring Water Breathing, as Drowned commonly guard the ruins.
Many ruins contain a loot chest, and some hold a buried-treasure map that leads to a Heart of the Sea — making a cluster of ruins a reliable early route to a Conduit.
Yes — both editions, Minecraft 26.2 (Java) and 1.26.30 (Bedrock). Markers read 99% on Java and 98% on Bedrock.
