Minecraft:Structure

File:21w07a Mineshaft.png

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 Template:Cmd and will not spawn in the world when the "Generate Structures" option is disabled during world creationTemplate:Only. Certain Minecraft:features, such as monster rooms or desert wells, still generate when this option is disabled and are listed under Template:Slink due to their resemblance to other defined structures.

Overworld

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

Underground structures

These structures can generate only underground in any default Overworld.

Structure	Biome(s)	Description	Screenshot
Template:EnvLink	Template:BiomeLink	Long corridors made of Minecraft:deepslate and Minecraft:wool, connecting to a central building with a frame like structure made of reinforced deepslate. The central structure resembles a Minecraft:warden. Small ruins can be found scattered around the ancient city containing loot Minecraft:chests inside. Since this structure generates in the deep dark biome, it contains many sculk sensors, shriekers, and catalysts.	width=300x300
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	A hidden Minecraft: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/gold ingots, emeralds, TNT and potions.	File:Buried Treasure Vibrant Visuals.png
Template:EnvLink	Any Minecraft:Overworld biome except Template:BiomeLink	A maze of corridors supported by wooden beams, with incomplete rail systems on which minecarts with chests can generate. Cave spider spawners may generate here heavily surrounded by Minecraft:cobwebs. In badlands biomes, they use dark oak planks instead of oak planks, and may generate close to the surface.	File:Mineshaft Vibrant Visuals.png
Template:EnvLink	Any Minecraft: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 Minecraft:End portal in the stronghold is the only way to access Minecraft:the End dimension, and it requires eyes of ender to activate. Eyes of ender are also used to locate the stronghold.	File:Stronghold Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink	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.	File:Trail Ruins Vibrant Visuals.png
Template:EnvLink	Any Minecraft:Overworld biome except Template:BiomeLink	A large underground structure made of copper and Minecraft:tuff-related blocks, featuring trial spawners and Minecraft:vaults in challenging combat rooms. It is the only place where the breeze is found, as well as the heavy core in vault loot.	File:Trial chambers VV.png

Above ground structures

These structures generate only aboveground.

Structure	Biome(s)	Description	Screenshot
Template:EnvLink	Template:BiomeLink Template:BiomeLinkTemplate:Only	Large Minecraft:sandstone buildings containing four Minecraft:chests with loot in an underground room hidden beneath Minecraft:terracotta. The chests are trapped with Minecraft: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.	File:Desert Pyramid Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink	Minecraft:Snow buildings that may have a basement hidden under a white carpet. The igloo itself contains little of value, but the basement has a Minecraft: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.	File:Igloo Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	Overgrown Minecraft:cobblestone structures containing two loot chests, with one trapped with two Minecraft:dispensers firing Minecraft:arrows by Minecraft:redstone and the other hidden behind a Minecraft:lever puzzle. Setting the correct combination for the Minecraft:lever puzzle moves a block on the main floor, revealing a hidden cavity and the Minecraft:chest.	File:Jungle Pyramid Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink peak biomes Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	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 Minecraft:chest on the top. 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.	File:Pillager Outpost Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLinkTemplate:Only	Swamp huts are small wooden buildings on top of log stilts containing a Minecraft:cauldron with a random Minecraft:potionTemplate:Only and crafting table. Upon their generation, one black cat and one Minecraft: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.	File:Swamp hut VV.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	A town full of houses and job sites inhabited by Minecraft: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.	File:Village Vibrant Visuals.png File:Abandoned Village Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	Massive, systematically-generated buildings constructed with dark oak and a cobblestone foundation. They contain many rooms (some hidden) and loot Minecraft: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.	File:Woodland Mansion Ingame.png

Aboveground and underground structures

These structures generate both aboveground and underground.

Structure	Biome(s)	Description	Screenshot
Template:EnvLink	Any Minecraft:Overworld biome except Template:BiomeLink	An incomplete Nether portal constructed with various types of Minecraft:stone materials. They can generate in varying sizes and positions, on the surface, underwater, and in caves. A Minecraft:netherrack platform generates underneath, as well as a loot chest and a few gold blocks.	File:Ruined Portal Vibrant Visuals.png

Underwater structures

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
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only	Massive Minecraft: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.	File:Ocean Monument Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only	A collection of small structures made of stone bricks or Minecraft: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.	File:Ocean Ruins Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only	Wooden structures resembling sunken ships in varying states of deterioration, containing up to three loot Minecraft:chests. Sometimes they can generate on land.	File:Shipwreck Vibrant Visuals.png

The Nether

Minecraft:The Nether, though equally vast, contains far fewer biomes and structures than the Overworld.

Structure	Biome(s)	Description	Screenshot
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLink	Enormous, castle-like Minecraft:blackstone structures housing Minecraft: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.	File:Bastion Remnant Vibrant Visuals.png
Template:EnvLink	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.	File:Nether Fortress Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink	Minecraft:Fossil variants that are more incomplete and purely composed of bone blocks. Dried ghasts may sometimes generate near Nether fossils. Template:IN, this is technically a feature rather than a structure feature.	File:Nether Fossil Vibrant Visuals.png
Template:EnvLink	All Nether biomes	Similar to the Overworld ruined portal, this is an incomplete Nether portal constructed with Minecraft:blackstone materials instead of stone. They can generate in varying sizes and positions, with a loot chest and a few gold blocks.	File:Nether Ruined Portal Vibrant Visuals.png

The End

Minecraft: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
Template:EnvLink	Template:BiomeSprite The EndTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	Sprawling, well-connected towers built from purpur blocks, End stone bricks, and magenta stained glass. They are inhabited by shulkers that guard valuable loot Minecraft:chests, and may generate an End ship holding a pair of Minecraft:elytra.	File:End City Vibrant Visuals.png

Structure-like features

Template:Main 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" optionTemplate:Only is disabled. These cannot be located using the Template:Cmd command.

Features	Biome(s)	Description	Screenshot
Template:EnvLink	All Minecraft:Overworld biomes	Large, hollow spherical rocks composed of outer layers of smooth basalt and Minecraft:calcite with an inner layer of amethyst blocks. This is the only place where budding amethyst and amethyst blocks can be found. They come in many sizes, including open geodes and entirely encased geodes.	File:Geode VV.png
Template:EnvLink	Any near the world spawn	A chest with beginner loot, that spawns near the Minecraft:world spawn if the feature was toggled on when creating the world.	File:Bonus Chest Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	Small Minecraft:sandstone feature holding Minecraft:water in their center cavity with suspicious sand below.	File:Desert Well Vibrant Visuals.png
Template:EnvLink	Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeSprite The End	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.	File:End Gateway Vibrant Visuals.png
Template:EnvLink	Template:BiomeSprite The End	Obsidian platform on which the player spawns when they enter the End.	File:Obsidian Platform Vibrant Visuals.png
Template:EnvLink	Template:BiomeSprite The End	Tall obsidian pillars that hold the End crystals. Some of them also have iron bars.	File:End Spike Vibrant Visuals.png
Template:EnvLink	Template:BiomeSprite The End	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.	File:Exit Portal Vibrant Visuals.png
Template:EnvLink	Template:BiomeLink Template:BiomeLink Template:BiomeLink Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only Template:BiomeLinkTemplate:Only	Usually buried feature made of bone blocks and coal or diamond ore depending on the altitude.	File:Fossil Vibrant Visuals.png
Template:EnvLink	All Minecraft:Overworld biomes	A small Minecraft:cobblestone room containing a monster spawner, which spawns Minecraft:zombies, skeletons, or spiders, as well as up to two loot Minecraft:chests. They are typically connected to underground caves but may generate above ground or intersected with true structures such as mineshafts or strongholds.	File:Monster room VV.png
Template:EnvLink	Template:BiomeSprite The Void	A platform made of Minecraft:stone with a Minecraft:cobblestone block in the center. They can spawn only in superflat worlds with "The Void" preset selected.	File:Void platform Vibrant Visuals.jpeg

Removed structures

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

Structure	Biome(s)	Description
Template:EnvLink	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.
Template:BlockLink	Any Minecraft:Overworld biome.	A tall, 1×1 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.
Template:EnvLink	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.
Template:EnvLink	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.
Template:EnvLinkTemplate: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 Minecraft:the Nether did not exist Template:In back then. It was then removed after the addition of the Nether in Pocket Edition.
Template:EnvLinkTemplate:Only	Anywhere where the Nether reactor was built.	A tall and round structure that spawned over the Nether reactor. It was made out of Minecraft:obsidian, which was later changed to Minecraft:netherrack. It would spawn various zombie pigmen and items from Minecraft:the Nether. Its purpose was to enable the players on Pocket Edition to obtain certain items, since the Nether was not implemented yet.
Template:EnvLink	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

Structures are generated for a given chunk after the terrain has been formed. The chunk format includes a tag called Template:Cd 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.
