How to use the Ocean Monument Finder
Ocean monuments only generate in deep ocean biomes with ocean all around. This finder marks every monument so you can plan a guardian farm or hunt for sponge rooms.
- Type or paste your seed in the seed box (numbers and text seeds both work), then pick your edition and version.
- Ocean monuments are marked on the map automatically. Drag to pan, scroll or pinch to zoom, and hover an icon to see its coordinates.
- Click an icon to copy the coordinates or a ready-made /tp command, and tick "Completed" to keep track of the ones you have visited.
- Use the "Nearest" list in the sidebar to jump straight to the closest ones to spawn or to any X/Z you enter.
Where monuments generate
On Java, monuments use regions of 32×32 chunks with a 5-chunk separation, and the chosen spot must be a deep ocean variant (deep ocean, deep cold, deep lukewarm or deep frozen). The surrounding area also has to be ocean, so monuments are common in big deep oceans and missing in small seas.
Cartographer villagers sell ocean explorer maps that point to the nearest monument, but the map here gives you all of them at once, so you can pick one close to your base.
What's inside
A monument is 58×58 blocks and is guarded by guardians and three elder guardians. Each elder guardian applies Mining Fatigue III, so kill them before mining. The treasure chamber in the center hides eight blocks of gold inside dark prismarine, and wet sponge rooms appear in many monuments.
There are no chests. The rewards are prismarine, sea lanterns, sponges, gold and, after draining, a perfect spot for a guardian farm. Bring Respiration, Depth Strider, potions of water breathing and night vision, and a stack of doors or sand for air pockets.

Questions
How big is an ocean monument?
58×58 blocks and 23 blocks tall. The marker is the monument's center, and the entrance faces south.
Does every monument have a sponge room?
No. Sponge rooms are optional, and roughly two thirds of monuments have at least one. The map cannot predict the interior.
Are monuments accurate on Bedrock?
Mostly. On Bedrock about 9 in 10 markers are confirmed in-game, and no real monument is missing, so check the marker and look for the next one if a spot is empty.
Where is the gold in an ocean monument?
In the central treasure chamber: eight gold blocks wrapped in dark prismarine. The chamber sits roughly in the middle of the monument, a few levels up from the floor.
How do I locate a monument with a command?
With cheats on, use /locate structure minecraft:monument on Java or /locate structure monument on Bedrock.
