version: "1.0.0" name: world_atlas description: Every structure and biome of Minecraft 1.21.1 with its exact registry id (all 34 structures and 64 biomes from the 1.21.1 registry), the ids people usually get wrong, the family tags, and a short picture of each - what is there, its dangers and its loot.

World atlas (1.21.1)

These are the complete vanilla lists for 1.21.1; an id that is not here is not vanilla (mods and datapacks can add more). Every id is in the minecraft: namespace. Structures are buildings with rooms and chests; biomes are regions of terrain and climate.

Ids that are easy to get wrong

Woodland mansion = minecraft:mansion (not woodland_mansion)
Ocean monument = minecraft:monument (not ocean_monument)
Jungle temple = minecraft:jungle_pyramid; desert temple = minecraft:desert_pyramid
Nether fortress = minecraft:fortress
There is no plain village: the five are village_plains, village_desert, village_savanna, village_snowy, village_taiga, and the tag #minecraft:village covers them all
The pale garden and the creaking do not exist in 1.21.1 (they arrived in 1.21.4)
