Minecraft Ocean Monument Finder
Find every Ocean Monument on your Minecraft seed — Java 26.3 & Bedrock 1.26.51, 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. 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, fully submerged near the sea floor. They need a large body of deep water, so they appear wherever your seed has open ocean.
How do I find an Ocean Monument with a seed?
Enter your seed and the finder marks every monument. Open a marker for coordinates and sail there — you will see the dark prismarine structure beneath the surface. Bring potions of Water Breathing and Night Vision before going in.
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 gold blocks and hidden rooms of sponge.
Does the finder work on Bedrock?
Yes — both editions, Minecraft 26.3 (Java) and 1.26.51 (Bedrock). The placement gate is slightly looser on Bedrock, so markers read 99% on Java and 90% on Bedrock.
