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.

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 ‌[Java Edition only] and in custom worlds the Mineshaft can generate aboveground in the void‌[Java Edition only]).

Small structures [ edit ]

These structures generate both aboveground (except the Buried Treasure) and Underground.

Underwater structures [ edit ]

These structures only generate underwater while the Shipwreck sometimes generates partly above water on shores.

Aboveground structures [ edit ]

These structures only generate aboveground (the Igloo does have an underground portion sometimes)

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 Zombie s, Skeleton s, or Spider s, 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. Uncommon Desert well Desert Small sandstone structures holding water in their center cavity. Rare

The Nether [ edit ]

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

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.

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.
