Generated structures
Reason: Include structure generation NBT fields
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; however, they are listed on this page due to them having the appearance of an artificial structure as opposed to a natural formation.
Contents
Overworld[edit]
The Overworld contains numerous generated structures, at a wide variety of scales.
Underground structures[edit]
These structures can only generate underground in normal worlds, although in Superflat they can generate above ground in Java Edition and in custom worlds mineshafts can generate aboveground in the void in Java Edition.
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Mineshaft | Any | 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. | Common |
Stronghold | Any | Maze-like stone bricks structures containing many rooms, including one with a usually unactivated end portal frame. They have a specific, fixed way of generating, and a maximum of 128 can generate in a single world.[Java Edition only] | Rare |
Amethyst Geode[upcoming: JE 1.17] | Any | 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. | Common |
Small structures[edit]
These structures generate both aboveground (except buried treasure) and underground.
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Fossil | Usually buried structures made of bone blocks and some coal ore. | Rare | |
Buried Treasure | 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. | Rare | |
Ruined Portal | Any | 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. | Common |
Underwater structures[edit]
Note that ocean ruins and shipwrecks sometimes generate above water on shores, and icebergs are partially above and below water.
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Iceberg |
|
A structure varying in size, consisting of packed ice and snow blocks, with blue ice on the bottom. | Uncommon |
Ocean Ruins | A collection of small structures made of stone bricks or sandstone. Drowned may spawn naturally here. | Common | |
Shipwreck |
|
Wooden structures resembling sunken ships in varying states of deterioration. They contain up to three loot chests, and may generate in underwater ravines[Bedrock Edition only]. | Common |
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. | Rare |
Aboveground structures[edit]
These structures only generate aboveground (the Igloo does have an underground portion sometimes)
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Desert Pyramid | Large sandstone buildings containing four loot chests in an underground room hidden beneath terracotta. The chests are trapped with TNT which detonate when the stone pressure plate in the center is stepped on, destroying the chests and their contents. | Uncommon | |
Igloo | Snow buildings that may have a basement hidden under carpet. The igloo itself contains nothing much of interest, but the basement has a villager and a zombie villager held captive behind iron bars. 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. | Rare | |
Jungle Temple |
|
Overgrown cobblestone structures containing two loot chests, with one trapped with two dispensers firing arrows 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. | Rare |
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 on 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. | Rare |
Swamp Hut |
|
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. | Rare |
Village |
|
A collection of houses and job sites inhabited by Villagers of random professions and one Iron Golem. 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. | Uncommon |
Woodland Mansion | 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. | Rare |
Miscellaneous structures[edit]
These structures generate even when the "Generate structures" world option is disabled, and also cannot be located with the /locate
command.
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Dungeon | Any | 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 other structures. | Common |
Desert well | Small sandstone structures holding water in their center cavity. | Uncommon | |
Forest rock | Small mossy cobblestone boulders randomly found throughout Giant Tree Taiga, often partially buried. | Uncommon |
The Nether[edit]
The Nether, though equally vast, contains far fewer generated structures than the Overworld.
Structure | Biome(s) | Description | Rarity |
---|---|---|---|
Nether Fortress | Any | 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 Blaze exclusively spawn here. | Uncommon |
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 spoils vary from one form to the next. | Uncommon | |
Nether Fossil | Fossil variants that are more incomplete and purely composed of bone blocks. | Common | |
Ruined Portal | Any | 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. | Common |
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 | Biome(s) | Description | Rarity |
---|---|---|---|
End City | 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. | Rare |
Technical details[edit]
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.
