Ocean Monument in Minecraft: Everything You Need to Know
Ocean Monuments are massive underwater structures found deep beneath Minecraft’s oceans. Built from prismarine blocks and guarded by powerful Elder Guardians, these monuments contain valuable resources, hidden rooms, sponges, and one of the game’s most challenging exploration experiences.
Quick Overview
- Ocean Monuments are large underwater structures.
- They generate in Deep Ocean biomes.
- Guardians and Elder Guardians protect the monument.
- Three Elder Guardians generate inside each monument.
- Monuments can contain sponges and a gold block treasure room.
What Is an Ocean Monument?
An Ocean Monument is a large structure that generates underwater in Minecraft. It is mainly built from prismarine, prismarine bricks, dark prismarine, and sea lanterns.
These monuments are heavily guarded and can be difficult to explore, especially for players who are not prepared for underwater combat. Guardians attack players with powerful beams, while Elder Guardians add another challenge through their special abilities.
Despite the danger, Ocean Monuments are worth exploring because they contain valuable blocks, rare sponges, and a hidden treasure room made with gold blocks.
Where Do Ocean Monuments Spawn?
Ocean Monuments generate underwater in Deep Ocean biomes. You will usually find them far from land, making exploration by boat one of the easiest ways to search for them.
Because monuments are large structures, parts of them can sometimes be visible from the surface when the water is clear enough.
Generation Tip
Ocean Monuments generate far out in the ocean, so travelling across Deep Ocean areas is the best way to find one naturally.
What Does an Ocean Monument Look Like?
Ocean Monuments are huge underwater buildings with a square-shaped central structure and several large wings extending from the sides. Their green-blue prismarine blocks make them easy to recognise.
The outside is surrounded by open water, while the inside contains tunnels, corridors, chambers, and randomly generated rooms.
| Feature | Description |
|---|---|
| Main Structure | A large prismarine building with multiple connected sections. |
| Central Area | The main section containing corridors and important rooms. |
| Wings | Large side sections where Elder Guardians can be found. |
| Hidden Rooms | Randomly generated rooms that may contain valuable resources. |
| Treasure Room | A hidden room containing blocks of gold. |
Which Mobs Guard an Ocean Monument?
Ocean Monuments are mainly guarded by Guardians and Elder Guardians. These hostile aquatic mobs can attack players underwater and make the monument dangerous to explore without preparation.
Guardians
Guardians are hostile mobs that swim through the water around and inside the monument. They attack players using a powerful beam and can also deal damage when attacked directly in certain situations.
Elder Guardians
Elder Guardians are larger and stronger versions of normal Guardians. Each Ocean Monument naturally generates with three Elder Guardians.
Defeating all three Elder Guardians is an important step when clearing a monument because they are responsible for the monument’s Mining Fatigue effect.
2. Elder Guardian
What Is Mining Fatigue?
Mining Fatigue is a status effect that makes breaking blocks extremely slow. Elder Guardians can apply this effect to nearby players, making it much harder to mine through the walls of an Ocean Monument.
This mechanic prevents players from quickly digging into the structure and encourages them to explore or fight their way through the monument.
Milk can remove Mining Fatigue, but Elder Guardians may apply the effect again while they are still alive and nearby.
How to Find an Ocean Monument
The best natural method is to explore large Deep Ocean areas. A boat can make searching easier, while maps and underwater exploration tools can help you identify structures beneath the surface.
Cartographer villagers can also provide Ocean Explorer Maps that point toward an Ocean Monument.
Using the Locate Command
If commands are enabled in your Minecraft world, you can locate a nearby Ocean Monument using the following command:
/locate structure minecraft:monumentMinecraft will provide coordinates for a nearby monument. The exact command syntax may vary depending on your Minecraft edition or version.
How to Enter an Ocean Monument
Before entering an Ocean Monument, make sure you have a reliable way to breathe underwater. Water Breathing potions, doors or other breathing methods can make exploration much easier.
Players can enter through existing openings or carefully explore the structure from the outside. Mining directly through walls is possible, but Mining Fatigue can make this extremely slow while Elder Guardians are alive.
What Loot Can You Find in an Ocean Monument?
Ocean Monuments do not use normal loot chests like many other Minecraft structures. Instead, their rewards come from valuable blocks, generated rooms, and resources collected from the monument itself.
| Reward | What You Can Find |
|---|---|
| Gold Blocks | A treasure room contains eight blocks of gold. |
| Sponges | Sponge rooms can generate with multiple wet sponges. |
| Prismarine | Large amounts of prismarine blocks can be collected. |
| Sea Lanterns | Decorative light blocks found throughout the monument. |
| Guardian Drops | Guardians can provide useful materials and prismarine-related drops. |
What Is a Sponge Room?
A Sponge Room is a special room that can generate inside an Ocean Monument. It contains several wet sponges attached to the room’s walls.
Sponge Rooms do not generate in every monument, so finding one can be especially useful. Sponges are valuable because they can quickly absorb large amounts of water.
Where Is the Gold Block Treasure Room?
Every Ocean Monument contains a hidden treasure room made with blocks of gold. The room is located inside the monument’s central structure.
The treasure consists of eight gold blocks arranged inside the room. Finding this area is one of the main reasons players explore Ocean Monuments.
How to Conquer an Ocean Monument
The safest strategy is to prepare before entering and deal with the Elder Guardians early. Once they are defeated, Mining Fatigue will no longer be applied by the monument’s Elder Guardians.
- Bring Water Breathing potions.
- Carry food and strong armor.
- Bring a weapon suitable for underwater combat.
- Look for and defeat the three Elder Guardians.
- Explore carefully for sponge rooms.
- Find the hidden gold block treasure room.
Ocean Monuments are much easier to clear when you prepare your underwater breathing and combat supplies before entering the structure.
Are Ocean Monuments Worth Exploring?
Yes. Ocean Monuments are one of the best structures to explore for players who want rare building blocks, sponges, gold, and Guardian resources.
They are also useful for players planning to build underwater bases or create Guardian farms later in the game.
