Generated Structures are randomly-generated features found throughout a Minecraft world. Generated structures can be found in many biomes, alternate dimensions, and can be either natural or manmade features. Some of these structures can be found by doing the /locate command using cheats on Java Edition.

Overworld Structures

The Overworld is home to many different generated structures. The following is a list of most of them, in alphabetical order.

Abandoned Mineshaft

A small part of a mineshaft.

Abandoned mineshafts are large, complex underground tunnels that contain wood, rails, and minecarts with chests filled with loot. In some cases, cave spider mob spawners can be found encased within a cluster of cobwebs. Some other mob spawners that are possible for a player to find are the zombie and skeleton. A mineshaft is a good place to find ores, considering that is probably what the mineshaft was originally used for. They frequently connect to a dungeon.

Dungeon

A dungeon.

Dungeons are small 5x5 (sometimes 7x7) rooms, that randomly generate underground, usually near an abandoned mineshaft or cave. Dungeons contain a mob spawner, which will spawn either zombies or skeletons, as well as two loot chests filled with random items, including some that are not craftable (such as a saddle or name tag).





Igloo

An igloo.

Igloos are randomly generated in ice plains biomes and cold taiga biomes. They are very small and simple and contain a bed, crafting table, furnace, and a redstone torch. Occasionally, breaking one of the carpets will reveal a ladder down to a basement. There is a villager next to a zombie villager, both in separate cells. A chest nearby contains a golden apple and other assorted loot, and a brewing stand nearby contains a splash potion of weakness. You can use these items to turn the zombie villager into a villager.

Natural Terrain

The terrain varies throughout the overworld, depending on the biome and world generator. Players can find hills, mountains, caves, ravines, and many other natural structures. Tree species and other natural structures like huge mushrooms also vary (or may not generate at all), depending on the biome. There is always a chance that a world seed will generate an Overworld containing extreme or unusual terrain.


Ocean Monument

An ocean monument.

Ocean monuments are underwater, pyramid-like structures, which randomly generate in ocean biomes. They consist of several types of rooms and hallways and are populated with guardians and Elder guardians. This is the only place in Minecraft where one can obtain a sponge.


Pillager Outpost

A pillager outpost.

The pillager outpost is a large structure that spawns with the pillager, a trapped iron golem, and an Illager captain. The pillager outpost spawns in every biome a village spawns in and they are mainly found near villages. The pillager outpost is mainly made up of dark oak planks and birch planks, torches, cobblestone, and mossy cobblestone, illager banners, dark oak Fences, cobblestone, and mossy cobblestone stairs, dark oak logs, vines, chests, crafting tables, and stone slabs.







Ruined Portal

An overworld ruined portal.

The Ruined Portal is a naturally generated structure with Obsidian, Crying Obsidian, etc. This structure was built long ago by an unknown person but it seems like something destroyed the Nether Portal. These Ruined Nether Portals generate in the Overworld, and in the Nether.







Shipwreck

A shipwreck.

The shipwreck is a structure that was added in 1.13 and can be found most everywhere in the ocean and, sometimes, even on land. They are sunken ships with chests containing loot such as suspicious stews and gold ingots. Shipwrecks are mainly made out of wooden logs and wooden planks.




Stronghold

A stronghold.

Strongholds are large structures that rarely generate underground. They contain an End portal, a player's only means of reaching the End. A player can also find chests and iron bars here. They contain a seemingly complex system of 3-block high by 3-block wide tunnels leading to sometimes abandoned libraries; most of the time to an intersection where many other tunnels meet.


Temples

Players can find two different types of temples in two different biomes throughout the Overworld. They are similar since both contain loot and traps.

Desert temples are found in desert biomes. They are pyramid-shaped and made of sandstone and colored clay. If a player manages to safely reach the bottom of the hidden loot room, without stepping on the pressure plate, they can retrieve treasure out of four chests (with one usually containing a Notch Apple). If a player steps on the pressure plate, it sets off TNT, which destroys all of the treasure.

Jungle temples are found in jungle biomes and are normally hidden within dense tree growth. The temple itself is made of mossy cobblestone and is covered in vines. Two chests of loot can be found inside. In order to reach them, the player must safely make their way through a tripwire and dispenser-filled corridor.


Underwater Ruins

WarmUnderwaterRuin.png

Formerly known as ocean ruins, they were added in the 1.13 Update and can be found almost anywhere in the ocean biomes. They can be found with stone, chiseled stone bricks, sea lanterns, sandstone, etc. These structures can spawn on sometimes land or in the ocean most likely. They spawn with chests containing some loot, the chest is hidden and you will need to dig to find it.

A new plains village structure.




Village

Villages consist of several different buildings, populated with various types of villagers, cats, and sometimes an Iron Golem. A village's appearance and layout vary based on the biome in which it generates. For example, a village that is generated within the desert will have houses built of sandstone, smooth sandstone, etc. instead of wood. Certain buildings within a village may or may not spawn, such as the tall "temple" or weaponsmith building.


Woodland Mansion

A woodland mansion.

Woodland mansions generate in the roofed forest biome. These structures contain hostile vindicator and evoker mobs, as well as multiple loot chests. They resemble a figure that contains 52 rooms, and several floors. This is NOT the only structure totems can be harvested at, rather the only place with pre-generated evokers.

End Structures

End City

An End city and a ship in the distance

An End city is a tall, tower-like structure that can vary slightly in both size and shape. There are two ways to get to the area where End cities spawn. One way to reach an End city is by defeating the Ender Dragon in the End and then using an Ender pearl to activate the portal. This will take players to the "outer End", where End cities can be located fairly easily. The other, more difficult way to reach an End city, is to build a bridge blocks long at the edge of the main island. This method takes a long time and requires many blocks. Also if unlucky, a player could be knocked off the edge of their bridge by an Enderman. End cities are hard to miss, with their bright-colored purpur blocks, and interesting spire designs. If a player is able to climb past the difficult shulker mobs and reach the top, they may find valuable treasure.

End Ship

An End ship.

There is a chance an End ship will generate above an End city. These structures contain a single elytra, other loot, a brewing stand with 2 potions of healing located in the rear entrance, and a dragon head located at the bow (front) part of the ship. Shulkers may spawn in or on the ship.

Obsidian Spawn

An obsidian platform.

When you enter the End, you will spawn on top of an obsidian platform before either building your way across, digging your way out, or get lucky enough and spawn very near the main End island.

Obsidian Pillars

These are the pillars where the end crystals that heal the dragon generate.

Bastion Remnant

A bastion remnant.

Bastion Remnants are structures that are the bases of Piglins and Hoglins that live here similar to the pillager outpost. Bastion Remnants can be found in any place in the Nether. As of update 1.16 (Nether Update), you can find three different types of bastion remnants: the Bridge Bastion, Treasure Bastion, Housing Units, and Hoglin Stables. The Bidge Bastion has a formation that looks like a pig snout to tell you which Bastion you are at. Inside you can find gold like every other Bastion and walkways riddled with lava. The Treasure Bastion contains as the name implies, treasure. This Bastion consists of two parts and multiple floors, in between the two sides is a bridge with gold blocks. The tall side has the most treasure with multiple double chests and a couple of single chests. In the main area, you can find a pile of gold in the center with lava surrounding it, along with a magma cube spawner. The Housing Units is a Bastion that contains lots of piglins but not as much loot, the Bastion is again split into two parts. The Hoglin Stables isTBastion is of three floors and contains a small amount of loot.

Huge Fungi

A warped huge fungus.

The Huge Fungi are structures that spawns in the Warped & Crimson Forests. The Warped varient of this structure has Warped stem, Warped wart, nether sprouts nearby, twisting vines and Shroomlights. The Crimson varient of this structure has crimson stem, Weeping vines, Nether wart blocks, and Shroomlights. Both variants can have nether roots generated nearby.







Nether Fortress

A nether fortress.

A Nether fortress is a relatively large structure containing loot chests in the corners of its corridors. Nether wart can be found planted next to staircases and in chests. The majority of a Nether fortress is made out of Nether bricks. Additionally, several other features can be found. Lava well rooms, blaze spawner rooms, collapsed bridges and balconies are all features of a Nether fortress. Wither skeletons, skeletons, Zombified piglins, blazes, and ghasts can spawn here as well.




Nether Fossil

A nether fossil.

The Nether Fossil is a structure that generates naturally in the Soul Sand Valley. This structure is made of Bone Blocks. This structure is the easiest way to obtain bone blocks.








Ruined Portal

A nether ruined portal.

The Ruined Portal is a naturally generated structure with Obsidian, Crying Obsidian, etc. This structure was built long ago by an unknown person but it seems like something destroyed the Nether Portal. These Ruined Nether Portals generate in the Overworld, and in the Nether.

Cave Structures

Stalagmites / Stalactites

Stalagmites and Stalactites are structures most likely made with Stone and Marble. Not much is known about them since they are part of the 1.17 Caves and Cliffs Update.
