How to Find an Ocean Monument in Minecraft
Ocean Monument TipsOcean Monuments are one of Minecraft’s most rewarding mid-to-late-game objectives — the combination of 8 hidden Gold Blocks, massive Prismarine block yields, and the potential for a permanent Guardian farm makes them worth the significant preparation they demand. The key investment before visiting is potions: Water Breathing and Night Vision transform an extremely frustrating underwater dungeon into a manageable one, and Milk for Mining Fatigue removal is non-negotiable. Once you have cleared your first Monument and understand the layout — three wings, a central treasure chamber, and Elder Guardian rooms scattered throughout — subsequent clears become much faster. The Ocean Explorer Map from a Cartographer remains the cleanest Survival route to locating one, and the Emerald cost is easily recouped from the Gold Blocks alone on your first successful raid.FAQ
⚡ Quick Answer
How to Find an Ocean MonumentThe fastest way to find an Ocean Monument is to use the command /locate structure minecraft:monument in Java Edition (or /locate monument in Bedrock) to get exact coordinates. Without commands, trade with a Cartographer villager for an Ocean Explorer Map — it marks the nearest Monument on the map. Ocean Monuments always spawn in Deep Ocean biomes, so sailing out to sea and looking for the large Prismarine structure underwater is the manual alternative.
1
Use /locate to find the nearest Monument instantly (Java & Bedrock). Open chat and type /locate structure minecraft:monument in Java Edition or /locate monument in Bedrock Edition. The game returns the coordinates of the nearest Ocean Monument immediately. This requires cheats enabled — either in a world with cheats on, or in Creative Mode. Once you have the coordinates, open your map or F3 debug screen (Java) to navigate directly to the X and Z values given.
2
Buy an Ocean Explorer Map from a Cartographer villager. A Journeyman-level Cartographer (green apron, third trade tier) sells an Ocean Explorer Map for 13 Emeralds + 1 Compass. This map marks the nearest Ocean Monument with an X — sail toward the X and the Monument is directly beneath it on the ocean floor. Farm Emeralds via other villagers first, then trade with the Cartographer. This is the best Survival method when cheats are off.
3
Search Deep Ocean biomes manually if you have no village. Ocean Monuments only generate in Deep Ocean and Deep Lukewarm Ocean biomes — never in regular Ocean or shallow water. Sail away from your spawn in any direction: the further from land you go, the more likely you are to enter Deep Ocean territory. Look for water that appears very dark blue-black — this indicates depth. Monuments are roughly 58×58 blocks wide and sit on the ocean floor, so dive down when you reach deep water and scan the seabed.
4
Look for the Monument’s silhouette from above. Ocean Monuments are large enough to be visible from the surface in clear water — their teal Prismarine colour stands out distinctly against the dark ocean floor. Brew a Potion of Night Vision before diving to make the Monument visible from much further away underwater. Night Vision is the single most useful potion for Ocean Monument exploration — without it, visibility underwater is extremely limited even in the daytime.
5
Prepare before entering — Guardians deal serious damage. Ocean Monuments are defended by Guardians (ranged laser attack) and Elder Guardians (inflict Mining Fatigue III, slowing your block-breaking). Before diving in, bring: Potion of Water Breathing (3 minutes minimum — brew 8-minute versions for full clears) · Potion of Night Vision · a sword with Smite or Sharpness · armour with Aqua Affinity and Respiration on the helmet. Milk from a Cow removes Mining Fatigue if an Elder Guardian curses you mid-raid.
6
Loot the Monument’s treasure rooms and 8 Gold Blocks. Each Ocean Monument contains 3 Elder Guardians that must be killed to remove the Mining Fatigue debuff permanently for that Monument. The main reward is 8 Gold Blocks hidden inside a Wet Sponge room at the Monument’s core — worth 72 Gold Ingots total. Additional loot includes Prismarine, Sea Lanterns, and Sponge blocks. After clearing all 3 Elder Guardians and collecting the Gold Blocks, the Monument is fully cleared and never respawns enemies.

Drink Milk immediately if you get Mining Fatigue: Elder Guardians apply Mining Fatigue III the moment you get close — it makes breaking blocks nearly impossible and severely limits your ability to navigate inside the Monument. Carry at least 3 Buckets of Milk and drink one immediately on application. Milk removes all potion effects including your own buffs, so reapply your Water Breathing and Night Vision potions right after drinking it.
→
Drain the Monument with Sponges for easier clearing: once you kill the first Elder Guardian and have some Sponge blocks, you can drain sections of the Monument by placing Sponges inside rooms — each Sponge absorbs a large cube of water. Draining rooms before fighting Guardians inside them makes combat significantly easier since you can move freely and they lose their home-terrain advantage. Dry wet Sponges in a Furnace to reuse them.
→
Build a base outside the Monument before raiding it: place a temporary base — a small sealed room — just outside the Monument entrance before diving in. Stock it with food, potions, Milk, and a Bed (if in a safe dimension). Having a nearby resupply point makes long Monument clears far more sustainable than trying to surface and swim back to shore between each Elder Guardian fight.

Monuments are great sources of Prismarine for builds: beyond the Gold Blocks, Ocean Monuments are the only source of Prismarine, Prismarine Bricks, Dark Prismarine, and Sea Lanterns in the game. If you want these blocks for decoration, bring a Pickaxe with Silk Touch to collect the blocks intact — without Silk Touch, Prismarine drops as Prismarine Shards instead of full blocks.
→
Convert a cleared Monument into a Guardian farm: after clearing all 3 Elder Guardians, Guardians continue spawning inside the Monument indefinitely — making it one of the best XP and Prismarine Shard farms in the game. Drain the Monument completely, build a water-flow system to funnel Guardians into a kill chamber, and you have a fully automated mob farm that produces thousands of Prismarine Shards and XP per hour.
How do you find an Ocean Monument in Minecraft without cheats?
Trade with a Journeyman-level Cartographer villager for an Ocean Explorer Map — it costs 13 Emeralds and 1 Compass and marks the nearest Ocean Monument with an X. Alternatively, sail into Deep Ocean biomes (very dark water far from land) and look for the large teal Prismarine structure on the seabed. Using a Potion of Night Vision while underwater makes it visible from much further away.
What biome do Ocean Monuments spawn in?
Ocean Monuments only spawn in Deep Ocean and Deep Lukewarm Ocean biomes. They never generate in regular Ocean, shallow water, or any land biome. Deep Ocean appears as very dark, almost black water when viewed from above — sail far from land in any direction until the water darkens significantly, then dive down to look for the Monument on the seabed.
What is the reward for clearing an Ocean Monument in Minecraft?
The main reward is 8 Gold Blocks (worth 72 Gold Ingots) hidden in the central treasure chamber. You also collect large quantities of Prismarine, Prismarine Bricks, Dark Prismarine, and Sea Lanterns from the structure itself. Killing all 3 Elder Guardians permanently removes the Mining Fatigue debuff from that Monument and allows you to convert it into a Guardian farm for ongoing XP and Prismarine Shard production.
How do you deal with Mining Fatigue at an Ocean Monument?
Drink a Bucket of Milk immediately when Mining Fatigue is applied — Milk removes all active potion effects including Mining Fatigue III. Carry at least 3 Milk Buckets when raiding a Monument. After drinking Milk, reapply your Water Breathing and Night Vision potions since Milk removes beneficial effects too. Killing all 3 Elder Guardians inside the Monument permanently prevents Mining Fatigue from being reapplied at that structure.
