Ocean monuments, also known as simply monuments, are rare underwater structures found in deep ocean biomes and variants. They are inhabited by guardians and elder guardians. They are the only place where sponges can be found and one of the two places where prismarine can be found; the other being ocean ruins.

Generation

Ocean monuments generate in areas with deep ocean biome variants everywhere within a 16 block square radius around the center point, and an aquatic biome (regular/deep/frozen ocean or regular/frozen river) everywhere within a 29 block square radius around the center point. In order to prevent air pockets, water generates around the monument as a part of the structure. The four blocks in the exact middle always generate each in a different chunk. It is the largest structure that does not contain a loot chest and the largest water structure. An ocean monument can also overwrite other structures like strongholds during generation. A maximum of one ocean monument may generate in every 512×512 block area.

In Bedrock Edition, ocean monuments always generate at the same Y-level, with the top of the roof always at Y=56. Seafloor surrounding the monument is cut off if it is higher than the monument's base.

They can be located with ocean explorer maps, which are bought from apprentice-level cartographer villagers with emeralds.

Elder Guardian Guardian

The area of the ocean monument spawns only guardians after generating, also being the only location they spawn. Ocean monuments always contain three elder guardians – one at the top and one in each wing.

in Bedrock Edition, the particle of the elder guardian inflicting Mining Fatigue III is a separate entity, the elder guardian ghost.

Structure

The treasure chamber with a sponge room (smaller dark prismarine room) to its left.

The monument is constructed entirely from variants of prismarine and lit by sea lanterns. It includes a large central section flanked by two wings. Under the monument are 23 giant pillars that stretch to the ocean floor. The main entrance is located at the front of the central section. The base size of the structure is 58×58 blocks. Thus, the ocean monument (the location where guardians and elder guardians spawn) area is 3,364 square blocks.

Certain rooms in the monument contain wet sponges.

The central section consists of various types of chambers. The chambers are randomly generated; each monument has a different number of rooms (at least six) arranged in a unique manner. The chambers connect vertically and horizontally to the different parts of the monument, including the left and right wings. At the topmost room resides an elder guardian. Around the center of the central section lies the treasure chamber, a tall room with eight blocks of gold encased in dark prismarine.

Occasionally, monuments contain one or more rooms with approximately 30 wet sponges on the ceiling. Sponge rooms have an opening only in the floor. Ocean monuments are not guaranteed to generate sponge rooms.

One of the wings contains a large room with a small pillar at the center. The room contains a second elder guardian. The other wing consists of a large open space with a large, square-shaped platform, containing another elder guardian. A long hallway that arcs around the wings and the back portion of the monument connects the two wings together.

History

Java Edition
1.814w25aAdded ocean monuments.[1]
At their addition, ocean monuments may generate in existing chunks with an InhabitedTime (i.e. the amount of time players have been in the chunk) of less than 3 minutes. They generate in locations that they would have generated in the current version of Minecraft, regardless of what terrain was originally there,[2] meaning they may generate inside large square pools of water surrounded by land, causing the terrain to be harshly cut off.[3]
1.8.2pre7Ocean monuments now generate correctly in customized worlds.[4]
1.915w46aOcean monuments now require a larger area of deep ocean at the center to generate.
