Igloo

Igloos are structures that are naturally generated in snowy biomes. They are small round structures constructed primarily of snow blocks.

Generation
Igloos naturally generate in the Snowy Tundra and Snowy Taiga biomes, but not in Snowy Mountains, Ice Spikes, Snowy Taiga Hills, or other variants.

Structure
Igloos are composed of snow blocks, sheltering a carpeted interior containing a bed, furnace and crafting table.

In half of the igloos, a trapdoor can be found under the carpet, leading down a long ladder shaft to a basement. This passageway and the basement are built from stone brick, some of which are infested blocks. In this basement there is a brewing stand, a cauldron, a chest, and beyond the far wall, behind iron bars in two different cages, are a villager and a zombie villager. The zombie villager can be cured with a golden apple and a splash potion of weakness, both found inside the igloo. In Java Edition, these are always priests and zombie priests, and in Bedrock Edition, they can be any type of villager or zombie villager.

The cauldron is $2/3$ full, and the brewing stand contains a splash potion of weakness.

One may access the individual structures of an igloo by using structure blocks to manually load them from the /data/structures/igloo folder in version.jar. To do so, set a structure block to Load mode, enter igloo/structure name, and press [LOAD]. The individual structures are bottom.

Trivia

 * If a number of items in the igloo furnace are smelted, light generated by it will melt the igloo window, turning the ice into a water source block.
 * In real life, the name "Igloo" comes from the Inuit word Iglu, which means "house".
 * Igloos are internally classified as a temple.
 * The igloo is the first structure to use signs.
 * As of Village and Pillage, igloos with basements are registered as villages, due to having one villager and beds. Additionally, basements also generate job site blocks, which are brewing stands and cauldrons.
 * The interior of the igloo is intentionally designed so that usage of the furnace melts the ice windows.
