Minecraft Ocean Monument Finder
Find every Ocean Monument on your Minecraft seed — Java 26.3 & Bedrock 1.26.62, any seed, free, no sign-up.
Quick answer: Ocean Monuments generate in deep ocean biomes in the Overworld, guarded by Guardians and three Elder Guardians. Half of worlds have one within 950 blocks of spawn on Java and 1,000 on Bedrock. This finder marks them at 99% accuracy on Java and 90% on Bedrock.
Where do Ocean Monuments spawn?
Ocean Monuments spawn only in deep ocean biomes in the Overworld — the deep frozen, cold, lukewarm and ordinary deep oceans — fully submerged near the sea floor. Shallow ocean never has one, so a seed has monuments wherever it has wide stretches of deep water.
How far from spawn is the nearest Ocean Monument?
Around 1,000 blocks for half of all worlds. Across 200 random worlds, half had an Ocean Monument within 950 blocks of spawn on Java and 9 in 10 had one within 1,900; on Bedrock the same figures are 1,000 and 1,950. Each 512 × 512-block area can hold one, but only where it lands in deep ocean, so a world averages about 1 within 1,000 blocks of spawn. Open a marker for coordinates and sail there — the dark prismarine shape shows beneath the surface. Bring potions of Water Breathing and Night Vision before going in.

| 9 worlds in 10 have one within | 1,900 blocks | 1,950 blocks |
| Worlds with one within 1,000 blocks | 5 in 10 | 5 in 10 |
| How many within 1,000 blocks, on average | About 1 | Less than 1 |
Measured with this finder on 200 random worlds in each edition, from the point where each world spawns you. Distances are rounded.
How rare are Ocean Monuments, and what guards them?
They are uncommon but reliably present wherever there is deep ocean. Each is guarded by Guardians and three Elder Guardians, which inflict Mining Fatigue, protecting a core of eight gold blocks and hidden rooms of wet sponge.
Are Ocean Monuments in the same place on Java and Bedrock?
No — the same seed puts its monuments in different places on each edition, so pick your edition above before you read coordinates. How far you travel is about the same on both: half of worlds have one within 950 blocks of spawn on Java and 1,000 on Bedrock. The finder covers Minecraft 26.3 on Java and 1.26.62 on Bedrock, and markers read 99% accurate on Java and 90% on Bedrock.
