Minecraft Ocean Ruins Finder
Find every Ocean Ruins on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Ocean Ruins generate submerged on the floor of every kind of ocean in the Overworld, sometimes hiding buried-treasure maps. One is rarely far away: half of worlds have one within 400 blocks of spawn on Java and 400 on Bedrock. This finder marks them at 99% accuracy on Java and 97% on Bedrock.
Where do Ocean Ruins generate?
Ocean Ruins generate on the sea floor in every kind of ocean in the Overworld, as scattered crumbled buildings. In lukewarm and warm oceans they are built from sandstone; in ordinary, cold and frozen oceans, from stone — and they often appear in small fields rather than alone.
How far from spawn are the nearest Ocean Ruins?
A few hundred blocks in most worlds. Across 200 random worlds, half had ocean ruins within 400 blocks of spawn on Java and 9 in 10 had them within 850; on Bedrock the same figures are 400 and 900. Ruins come in clusters wherever there is ocean, so a world averages about 9 within 1,000 blocks. Open a marker for coordinates and dive in — bring Water Breathing, as Drowned commonly guard the ruins.

| Half of worlds have one within | 400 blocks | 400 blocks |
| 9 worlds in 10 have one within | 850 blocks | 900 blocks |
| Worlds with one within 1,000 blocks | 9 in 10 | 9 in 10 |
| How many within 1,000 blocks, on average | About 9 | About 9 |
Measured with this finder on 200 random worlds in each edition, from the point where each world spawns you. Distances are rounded.
What loot is inside Ocean Ruins?
Many ruins contain a loot chest, and a little under half of those chests 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. The rest of the chest is coal, wheat, gold nuggets and the odd emerald, fishing rod or enchanted book.
Are Ocean Ruins the same on Java and Bedrock?
How far you swim is about the same on both, but the same seed puts its ruins in different places on each edition, so pick your edition above before you read coordinates. The chests differ too: on Bedrock every ruin chest also holds a piece of nautilus armour (copper most often, diamond rarely), while on Java only about one chest in five does. The finder covers Minecraft 26.3 on Java and 1.26.62 on Bedrock, and markers read 99% accurate on Java and 97% on Bedrock.
