Minecraft Ocean Monument Finder
By the ChunkScan Team · Updated October 2026
Quick answer: To find an ocean monument, enter your world seed on this page and choose Java or Bedrock: the map marks every monument in reach. Monuments only generate in deep ocean, so look out to sea and zoom out if none shows. Link straight to a result with /ocean-monument-finder?seed=YOUR_SEED.
Ocean monuments are the only source of sponges and the place to build a guardian farm. This finder maps them for any seed, entirely in your browser, so your seed is never sent to a server. Monuments only generate in deep ocean, so the map opens 2,000 blocks wide; zoom out if none shows yet. Positions differ between Java and Bedrock for the same seed, so pick your edition first.

Why find an ocean monument?
Ocean monuments are the only source of sponges and the place to build a guardian farm for prismarine and XP. The central room hides eight gold blocks. Three elder guardians give you mining fatigue, so bring milk.
Where do ocean monuments spawn?
Monuments generate only in deep ocean biomes, with ocean or river all around them, on the sea floor. Enter your seed above and look for the nearest deep ocean: the map marks every monument with its coordinates.
Are ocean monuments the same on Java and Bedrock?
Ocean monuments generate in both editions, but the same seed places them differently on Java and Bedrock, so choose your edition above before you set sail. Sponges and guardians are the same on both platforms.
