Generated structures

This page lists generated structures in Minecraft. A generated structure is defined as any structure that is disabled when the "Generate structures" world creation option is turned off. Some structures such as dungeons and desert wells do still generate with this option turned off but are listed on this page due to them having the appearance of a structure as opposed to a natural formation.

The Overworld[edit]

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

Large underground structures[edit]

Structure Location Description
Mineshaft Underground in any biome. Contains long passageways with rails on the ground, some with minecarts with chests on them. Cave spider spawners may generate here surrounded by cobwebs.
Stronghold Underground in any biome; a maximum of 128 can generate in a single world.‌[JE only] Stone brick structures containing many rooms including an end portal room.

Small structures[edit]

Structure Location Description
Fossil Underground in Deserts and Swamps. Structures made of bone blocks and coal ore.
Buried treasure Under beaches. A chest containing loot, found using a treasure map.
Shipwreck In oceans. Wooden structures containing a few loot chests.

Buildings[edit]

Buildings are naturally generating structures that form above ground. They can contain valuable treasure, but traps and puzzles as well.

Structure Location Description
Desert pyramid In desert biomes. Large sandstone buildings containing four loot chests in an underground room trapped with TNT.
Igloo In snowy biomes. Snowy buildings with a villager and zombie villager in iron bar cages in an underground room. A loot chest contains a golden apple which can be used to cure the zombie villager.
Jungle pyramid In jungle biomes. Cobblestone structures which contain two loot chests trapped with dispensers firing arrows. Also contains a lever puzzle that contains a loot chest
Monument In ocean biomes. Large prismarine structures containing guardians and treasure
Pillager outpost In plains, desert, savanna, taiga, snowy tundra, and snowy taiga biomes. Tall wood and cobblestone structures which spawn pillagers.
Witch hut In swamp biomes. A small wooden building containing a cauldron which spawns witches.
Ocean ruins In ocean biomes. A collection of structures made of stone bricks which spawn drowneds.
Village In plains, desert, savanna, swamp, taiga, snowy tundra, and snowy taiga biomes. A collection of buildings containing villagers.
Mansion In dark forests. Very large dark oak wood structures containing many rooms, inhabited by illagers.

Quasi-structures[edit]

These structures will generate even when the "Generate structures" world option is disabled, and also cannot be located with the /locate command.

Structure Location Description
Dungeon Underground in any biome, connected to caves. A cobblestone room with a mob spawner inside. Contains two loot chests.
Desert well In desert biomes. A small sandstone structure containing a single block of water in the middle.

The Nether[edit]

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

Structure Location Description
Fortress Anywhere in the Nether. A large nether brick structure which spawns wither skeletons and contains blaze spawners.

The End[edit]

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 Location Description
End city In the End's outer islands. Tall purpur and end stone structures containing shulkers.
End ship Next to End cities. Purpur structures with shulkers and two loot chests.

Technical details[edit]

Cleanup.svg
This section may need cleanup to comply with the style guide. Please help us clean up this page if you can. The specific instructions are:
Remove information not related to generated structures.

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, they will be generated 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 will approximately double the amount of ore in it.

When structures are generated, they can spill over into neighboring chunks that have been previously generated. Thus, a tree at the edge of the generated world (and probably only visible using external tools) may be overwritten by a lake before the player reaches it. It is also theoretically possible for two worlds generated with the same seed, from the same version of Minecraft, to differ slightly depending on the players' travel routes, because the order in which chunks are generated may determine which of two conflicting structures will overwrite or suppress the other.

Trivia[edit]

  • In previous versions, before snow cover was solid, a lava lake with floating snow cover above it could be a deadly trap before the snow melted.
