Generated structures

It has been suggested that this page be moved to Structure.
If this move affects many pages or may potentially be controversial, do not move the page until a consensus is reached. ^[discuss^]

Reason: We have Biome - Custom biome, Dimension - Custom dimension, World preset - Custom world preset, etc. Why not Structure - Custom structure
And "generated structure" is not an official name.
When moving, be sure to use the appropriate tool instead of simply copying and pasting the page's contents, to preserve edit history.

This page lists structures (aka. generated structures, structure features) in Minecraft. A structure is defined as what is disabled when the "Generate structures" world creation option is turned off. Features, such as dungeons and desert wells, do still generate with this option turned off; however, they are listed on this page in #Structure-like Features due to them having the appearance of an artificial structure as opposed to a natural formation.

Overworld

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

Underground structures

These structures can only generate underground in vanilla default overworlds.

Structure	Biome(s)	Description
Ancient City	Deep Dark	It's made up of long corridors made of deepslate and wool. It has a central building with a portal like structure made of reinforced deepslate. the central structure resembles a warden. Small ruins can be found with 1-2 loot chests inside.
Mineshaft	Any overworld biomes except Deep Dark	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 cobwebs. In Badlands biomes, they use dark oak planks instead of oak planks, and may generate close to the surface.
Stronghold	Any overworld biomes	Maze-like stone bricks structures containing many rooms, including one with a usually unactivated end portal frame. In Java Edition, they have a specific, fixed way of generating, and a maximum of 128 can generate in a single world.
Buried Treasure	Beach Snowy Beach Stony Shore‌^{[BE only]} Mushroom Field Shore‌^{[BE only]}(Unused)	A single hidden chest containing valuable loot that spawn in beach/shore biomes. They are easily found using treasure maps located in shipwrecks and occasionally ocean ruins.

Aboveground structures

These structures only generate aboveground.

Structure	Biome(s)	Description
Desert Pyramid	Desert Desert Hills‌^{[BE only]}(Unused)	Large sandstone buildings containing four chests with loot in an underground room hidden beneath terracotta. The chests are trapped with TNT which detonate when a stone pressure plate in the center is stepped on, destroying the chests and their contents.
Igloo	Snowy Plains Snowy Taiga Snowy Slopes	Snow buildings that may have a basement hidden under a carpet. The igloo itself contains nothing much of value, but the basement has a villager and a zombie villager held captive behind iron bars with a sign saying to cure the zombie villager. The splash potion of weakness on the brewing stand, together with the golden apple in the loot chest, can be used to cure the zombie villager, and turn it back into a regular villager.
Jungle Temple	Jungle Bamboo Jungle‌^{[JE only]} Jungle Hills‌^{[BE only]}(Unused)	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.
Pillager Outpost	Plains Desert Savanna Taiga Snowy Plains Grove Meadow Frozen Peaks Jagged Peaks Stony Peaks Snowy Slopes Snowy Taiga‌^{[BE only]} Sunflower Plains‌^{[BE only]} Taiga Hills‌^{[BE only]}(Unused) Snowy Taiga Hills‌^{[BE only]}(Unused)	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 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 couple of allays.
Swamp Hut	Swamp	Also known as witch huts, these are small wooden buildings on log stilts containing a cauldron and crafting table. It spawns witches and, upon generation, one black cat. The cat and the first witch do not despawn naturally. You can use these witch huts to create a witch farm, as the witches will spawn automatically.
Village	Plains Meadow Desert Savanna Taiga Snowy Plains Snowy Taiga‌^{[BE only]} Sunflower Plains‌^{[BE only]} Taiga Hills‌^{[BE only]}(Unused) Snowy Taiga Hills‌^{[BE only]}(Unused)	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, depending on the biome that they generate in. Although village buildings do not have variants for jungle and swamp biomes, villagers wear different outfits when spawning in said biomes.
Woodland Mansion	Dark Forest Dripstone Caves‌^{[BE only]} Lush Caves‌^{[BE only]} Dark Forest Hills‌^{[BE only]}(Unused)	Massive, systematically-generated buildings constructed with dark oak wood and a cobblestone foundation. They contain many rooms (some hidden) and loot chests in their three floors, and are inhabited by vindicators and evokers that do not naturally despawn. Allays can sometimes be found in prison cells.

Aboveground and Underground structures

These structures generate both aboveground and underground.

Structure	Biome(s)	Description
Ruined Portal	Any overworld and nether biomes except Deep Dark	An incomplete nether portal constructed with various types of stone or blackstone materials when generating in the Overworld or Nether respectively. They can generate in varying sizes and positions. A netherrack platform underneath, as well as a loot chest and a few gold blocks, often generates.

Underwater structures

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

Structure	Biome(s)	Description
Ocean Ruins	Deep Ocean Deep Frozen Ocean Deep Cold Ocean Deep Lukewarm Ocean Ocean Frozen Ocean Cold Ocean Warm Ocean Lukewarm Ocean Deep Warm Ocean‌^{[BE only]}(Unused)	A collection of small structures made of stone bricks or sandstone. Drowned may spawn naturally here.
Shipwreck	Deep Ocean Deep Frozen Ocean Deep Cold Ocean Deep Lukewarm Ocean Ocean Frozen Ocean Cold Ocean Warm Ocean Lukewarm Ocean Beach Snowy Beach Mushroom Field Shore‌^{[BE only]}(Unused)	Wooden structures resembling sunken ships in varying states of deterioration, containing up to three loot chests.
Ocean Monument	Deep Ocean Deep Frozen Ocean Deep Cold Ocean Deep Lukewarm Ocean Deep Warm Ocean‌^{[BE only]}(Unused)	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.

The Nether

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

Structure	Biome(s)	Description
Nether Fortress	Any nether biomes	Towering nether brick castles that exclusively contain blaze 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.
Bastion Remnant	Nether Wastes Crimson Forest Warped Forest Soul Sand Valley	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 spoils vary from one form to the next.
Nether Fossil	Soul Sand Valley	Fossil variants that are more incomplete and purely composed of bone blocks. Note that in Bedrock Edition it's a feature rather than a structure feature.
Ruined Portal	Any overworld and nether biomes	An incomplete nether portal constructed with various types of stone or blackstone materials when generating in the Overworld or Nether respectively. They can generate in varying sizes and positions. A netherrack platform underneath, as well as a loot chest and a few gold blocks, often generates.

The End

The End is the final and most barren dimension, with no generated structures on its main island. After defeating the ender dragon, gateways to the outer islands are created.

Structure	Biome(s)	Description
End City	End Midlands‌^{[JE only]} End Highlands‌^{[JE only]} The End‌^{[BE only]}	Sprawling, well-connected towers built from purpur, end stone bricks and Purple Stained Glass. They are inhabited by shulkers that guard valuable loot chests, and the largest, most meandering cities may generate an end ship holding a pair of elytra.

Structure-like Features

These worldgen features have similarities to structures but they are not true structures. Instead, they are coded and generated the same way as trees or ores. This is why they generate even when the "Generate structures" world option is disabled, and also cannot be located with the /locate command.

Features	Biome(s)	Description
Dungeon	All Overworld Biomes	A small cobblestone room containing a 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.
Desert well	Desert	Small sandstone feature holding water in their center cavity. They do not generate gold or treasure as part of their generation but the water can be used as an infinite water source.
Forest rock	Old Growth Spruce Taiga Old Growth Pine Taiga	Small mossy cobblestone boulders randomly found throughout Old Growth Taiga, often partially buried.
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 and amethyst blocks can be found. They come in many sizes, including open geodes and entirely encased geodes.
Fossil	Desert Swamp	Usually buried feature made of bone blocks and some coal ore.
Iceberg	Frozen Ocean (all variants)	A feature varying in size, consisting of packed ice and snow blocks, with blue ice on the bottom. Note, not all iceberg-looking terrain in Frozen Ocean Biome are created by feature but as part of the biome itself through Surface Builders.

Technical details

This article needs to be updated.

Please update this page to reflect recent updates or newly available information.

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.
