A mineshaft generating across a large cave.

Structures (also known as a "generated structure" or "structure feature") are naturally-generated formations that can be located using /locate structure and will not spawn in the world when the "Generate Structures" option is disabled during world creation.โ€Œ[JE only] Players can generate structures using /place. Certain features, such as monster rooms or desert wells, still generate when this option is disabled and are listed under ยง Structure-like features due to their resemblance to other defined structures.

Overworld

[edit | edit source]

The Overworld contains numerous structures, at a wide variety of scales.

Underground structures

[edit | edit source]

These structures can generate only underground in any default Overworld.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
Ancient City
Long corridors made of deepslate and wool, connecting to a central building with a frame like structure made of reinforced deepslate. The central structure resembles a warden. Small ruins can be found scattered around the ancient city containing loot chests inside. Since this structure generates in the deep dark biome, it contains many sculk sensors, shriekers, and catalysts. ๐Ÿ‘ Image
๐Ÿ‘ Image
Buried Treasure
A hidden chest containing valuable loot that spawn in coastal biomes. They are found using treasure maps located in shipwrecks and occasionally ocean ruins. The most notable item in buried chests are the heart of the sea, which is guaranteed to be found. Other common loot that can be found are diamonds, iron and gold ingots, emeralds, TNT, and potions. ๐Ÿ‘ Image
๐Ÿ‘ Image
Mineshaft
Any Overworld biome except ๐Ÿ‘ Image
Deep Dark
A maze of corridors supported by oak fences, with incomplete rail systems on which minecarts with chests can generate. Cave spider spawners may generate here heavily surrounded by cobwebs. In badlands biomes, they use dark oak planks instead of oak planks, and may generate close to the surface. ๐Ÿ‘ Image
๐Ÿ‘ Image
Stronghold
Any Overworld biome Strongholds in Minecraft are generated with maze-like underground structures composed of various specialized rooms, including the essential End portal room, libraries, prison cells, and storage areas. The End portal in the stronghold is the only way to access the End dimension, and it requires eyes of ender to activate. Eyes of ender are also used to locate the stronghold. ๐Ÿ‘ Image
๐Ÿ‘ Image
Trail Ruins
A group of ruined buildings meant to resemble small, ancient settlements. The entire structure is buried underground except for the tip of the tower, which is exposed to the surface. The structure can contain suspicious gravel with various archaeology items. ๐Ÿ‘ Image
๐Ÿ‘ Image
Trial Chambers
Any Overworld biome except ๐Ÿ‘ Image
Deep Dark
A large underground structure made of copper and tuff-related blocks, featuring trial spawners and vaults in challenging combat rooms. It is the only place where the breeze is found, as well as the heavy core in vault loot. ๐Ÿ‘ Image

Above ground structures

[edit | edit source]

These structures generate only aboveground.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
Desert Pyramid
Large sandstone buildings containing four chests with loot in an underground room hidden beneath terracotta. The chests are trapped with TNT that detonates when a stone pressure plate in the center is stepped on, destroying the chests and their contents. There is also a buried side room with suspicious sand. ๐Ÿ‘ Image
๐Ÿ‘ Image
Igloo
Snow buildings that may have a basement hidden under a white carpet. The igloo itself contains little of value, but the basement has a villager and a zombie villager held captive behind iron bars. Acting as a tutorial, the basement contains all ingredients to cure the zombie villager, including a splash potion of Weakness on a brewing stand and golden apple in a chest. ๐Ÿ‘ Image
๐Ÿ‘ Image
Jungle Pyramid
Overgrown cobblestone structures containing two loot chests, with one trapped with two dispensers firing arrows by redstone and the other hidden behind a lever puzzle. Setting the correct combination for the lever puzzle moves a block on the main floor, revealing a hidden cavity and the chest. ๐Ÿ‘ Image
๐Ÿ‘ Image
Pillager Outpost
An assortment of structures spawning pillagers. The main feature of interest is the watchtower: a tall structure built with wood and cobblestone that generates a loot chest in the top floor. Located around the watchtower are up to four small structures, including tents, target scarecrows, and wooden cages sometimes containing an iron golem or a group of up to 3 allays. ๐Ÿ‘ Image
๐Ÿ‘ Image
Swamp Hut
Swamp huts are small wooden buildings on top of log stilts containing a cauldron with a random potionโ€Œ[BE only] and crafting table. Upon their generation, one black cat and one witch occupy the structure's area and the mobs do not despawn naturally. The huts can be used to create a witch farm, as replacement witches spawn automatically. ๐Ÿ‘ Image
๐Ÿ‘ Image
Village
A town full of houses and job sites inhabited by villagers with random professions and up to two iron golems defending the village. They are constructed with a wide variety of materials and different architecture, depending on the biome that they generate in. Villages also contain farms with animals and crops, and cats spawn commonly around the houses.

Villages can rarely generate as abandoned villages where zombie villagers spawn instead of villagers. Houses no longer have torches, some blocks are broken and replaced with cobwebs or mossy cobblestone, and no iron golems spawn.

๐Ÿ‘ Image

๐Ÿ‘ Image

๐Ÿ‘ Image
Woodland Mansion
Massive, systematically-generated buildings constructed with dark oak and a cobblestone foundation. They contain many rooms (some hidden) and loot chests scattered across their three floors, and are inhabited by vindicators and evokers that do not naturally despawn or respawn when defeated. Allays can sometimes be found in prison cells. ๐Ÿ‘ Image
๐Ÿ‘ Image
Abandoned Camp
โ€‹[upcoming: Third Drop 2026]
A small tent full of items, from oxidized copper golem statues to utility blocks, such as the crafting table, cauldron, and barrels. Abandoned camps are usually built out of wool stairs and fences, and have different appearances for each biome.

๐Ÿ‘ Image

Aboveground and underground structures

[edit | edit source]

These structures generate both aboveground and underground.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
Ruined Portal
Any Overworld biome except ๐Ÿ‘ Image
Deep Dark
An incomplete Nether portal constructed with various types of stone materials. They can generate in varying sizes and positions, on the surface, underwater, and in caves. A netherrack platform generates underneath, as well as a loot chest and a few gold blocks. ๐Ÿ‘ Image

Underwater structures

[edit | edit source]

These structures generate below the sea level i.e. y=64 and in the Ocean biomes.

Note that ocean ruins and shipwrecks sometimes generate above water on shores, and icebergs are partially above and below water.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
Ocean Monument
Massive prismarine temples inhabited by guardians, as well as three elder guardians in fixed positions. Wet sponges, along with eight blocks of gold as treasure, also generate naturally here. The interior structure is randomly generated, resembling a maze of sorts. ๐Ÿ‘ Image
๐Ÿ‘ Image
Ocean Ruins
A collection of small structures made of stone bricks or sandstone depending on the ocean temperature. Drowned may spawn naturally here. Along with loot chests, they contain suspicious sand or suspicious gravel. Suspicious sand in warm ocean ruins is the only way to get the sniffer egg. ๐Ÿ‘ Image
๐Ÿ‘ Image
Shipwreck
Wooden structures resembling sunken ships in varying states of deterioration, containing up to three loot chests. Sometimes they can generate on land. ๐Ÿ‘ Image

The Nether

[edit | edit source]

The Nether, though equally vast, contains far fewer structures than the Overworld.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
Bastion Remnant
Enormous, castle-like blackstone structures housing piglins and piglin brutes. They can generate in various forms (bridges, housing units, hoglin stables, and treasure rooms) and chest loot varies from one form to the next. Large quantities of gold blocks generate within the structure and this is the only place where netherite upgrades can be found. ๐Ÿ‘ Image
๐Ÿ‘ Image
Nether Fortress
All Nether biomes Towering castles made of Nether bricks that contain blaze monster spawners and Nether wart farms. They are divided into open-air ramparts and winding interior corridors, some of which contain loot chests. Wither skeletons and blazes exclusively spawn here. ๐Ÿ‘ Image
๐Ÿ‘ Image
Nether Fossil
Fossil variants that are more incomplete and purely composed of bone blocks. Dried ghasts may sometimes generate near Nether fossils.

In Bedrock Edition, this is technically a feature rather than a structure-like feature.

๐Ÿ‘ Image
๐Ÿ‘ Image
Ruined Portal
All Nether biomes Similar to the Overworld ruined portal, this is an incomplete Nether portal constructed with blackstone materials instead of stone. They can generate in varying sizes and positions, with a loot chest and a few gold blocks. ๐Ÿ‘ Image

The End

[edit | edit source]

The End is the final and most barren dimension. After defeating the ender dragon, gateways to the outer islands are created.

Structure Biome(s) Description Screenshot
๐Ÿ‘ Image
End City
Sprawling, well-connected towers built from purpur blocks, End stone bricks, and magenta stained glass. They are inhabited by shulkers that guard valuable loot chests, and may generate an End ship holding a elytra. ๐Ÿ‘ Image

Structure-like features

[edit | edit source]
Main article: Feature

These world generation features share similarities with structures but are generated in the same manner as trees and ores. They will generate even when the "Generate Structures" optionโ€Œ[JE only] is disabled. These cannot be located using the /locate command.

Features Biome(s) Description Screenshot
๐Ÿ‘ Image
Amethyst Geode
All Overworld biomes Large, hollow spherical rocks composed of outer layers of smooth basalt and calcite with an inner layer of amethyst blocks. This is the only place where budding amethyst, amethyst buds, amethyst clusters and amethyst blocks can be found. They come in many sizes, including open geodes and entirely encased geodes. ๐Ÿ‘ Image
๐Ÿ‘ Image
Bonus Chest
Any near the world spawn A chest with beginner loot, that spawns near the world spawn if the feature was toggled on when creating the world. ๐Ÿ‘ Image
๐Ÿ‘ Image
Desert Well
Small sandstone feature holding water in their center cavity with suspicious sand below. ๐Ÿ‘ Image
๐Ÿ‘ Image
End Gateway
A 1-block portal that activates after the ender dragon is defeated. Using an ender pearl, the player can teleport to the outer regions of the End. They generate infinetely throughout the world as gateways back to the main island. ๐Ÿ‘ Image
๐Ÿ‘ Image
End Platform
An obsidian platform that repairs itself when any entity enters the End. ๐Ÿ‘ Image
๐Ÿ‘ Image
End Spike
Tall obsidian pillars that hold the End crystals. Some of them also have iron bars. ๐Ÿ‘ Image
๐Ÿ‘ Image
Exit portal
A feature that looks like a fountain. It becomes the only portal to the Overworld and a dragon egg spawns on it after the player defeats the ender dragon. ๐Ÿ‘ Image
๐Ÿ‘ Image
Fossil
Usually buried feature made of bone blocks and coal or diamond ore depending on the altitude. ๐Ÿ‘ Image
๐Ÿ‘ Image
Monster Room
All Overworld biomes A small cobblestone room containing a monster spawner, which spawns zombies, skeletons, or spiders, as well as up to two loot chests. They are typically connected to underground caves but may generate above ground or intersected with true structures such as mineshafts or strongholds. ๐Ÿ‘ Image
๐Ÿ‘ Image
Void start platform
A platform made of stone with a cobblestone block in the center. They can spawn only in superflat worlds with "The Void" preset selected. ๐Ÿ‘ Image

Removed structures

[edit | edit source]

These are structures that have been removed or exist only in older versions of Minecraft.

Structure Biome(s) Description
๐Ÿ‘ Image
Brick Pyramid
Anywhere, since biomes did not exist at the time. A giant pyramid that had no interior and was made solely out of bricks. It was made to test structure generation. The official name for this structure is unknown. Was removed in Java Edition Infdev 20100327.
๐Ÿ‘ Image
Glass Pillar
Any Overworld biome. A tall, 1ร—1 glass pillar that stretched from the End portal room in the stronghold all the way to the build limit. According to Jeb, it was a debug feature that he forgot to remove. It was removed in the version Java Edition Beta 1.9 Prerelease 4.
๐Ÿ‘ Image
Starting House
Anywhere on the Java Edition Indev world. Used to serve as the spawn location for the player during the Indev phase. The first edition of this house was made of mossy cobblestone, but later it was changed to wooden planks. It also originally included chests with various items, which were later removed.
๐Ÿ‘ Image
Monolith
Anywhere during Infdev. Chunk-sized patches of terrain that would generate up to the height limit. They were never intended to be in the game as they were just a "glitch". Monoliths were patched in the version Alpha v1.2.0 Preview.
๐Ÿ‘ Image
Nether Reactor
โ€Œ[BE only]
Anywhere, as it's built by the player. A player-built structure that would turn into the "Nether Spire", and would give the player access to unobtainable items. The reason for its addition is because the Nether did not exist in Pocket Edition back then. It was then removed after the addition of the Nether in Pocket Edition.
๐Ÿ‘ Image
Nether Spire
โ€Œ[BE only]
Anywhere where the Nether reactor was built. A tall and round structure that spawned over the Nether reactor. It was made out of obsidian, which was later changed to netherrack. It would spawn various zombie pigmen and items from the Nether. Its purpose was to enable the players on Pocket Edition to obtain certain items, since the Nether was not implemented yet.
๐Ÿ‘ Image
Obsidian Wall
Anywhere, since it stretched toward every direction. A 2 block tall obsidian wall that was present during some versions of the Infdev phase. It started in the middle of the world, and stretched toward north, south, west and east. This structure doesn't have an official name.

Generation

[edit | edit source]

Structures are generated for a given chunk after the terrain has been formed. The chunk format includes a tag called TerrainPopulated that indicates whether structures whose "point of origin" is in that chunk have been generated. If it is false or missing, it generates again. Structure generation is based on what is already in the chunk, so (for example) flagging a chunk that has already been populated for repopulation approximately doubles the amount of ore in it. When structures are generated, they can spill over into neighboring chunks that have been previously generated.

Data values
