Witch Huts are a rare type of generated structure in Minecraft. They spawn in Swamp Biomes, and very rarely other biomes. They were the only place Witches could spawn before 1.7.2
InsideWitch Huts are made of spruce wood planks and are on top of Oak Wood stilts. They have a Cauldron and a Crafting Table in the corner, with a Mushroom in a Flower Pot on the window sill. It is dark enough for Mushrooms to spread.
Witch huts are often utterly deserted, making them a fair place to spend the night. However, the player may have to defeat a witch first.
