Iron farm in Minecraft

Iron farms automatically generate iron through the controlled spawning and killing of iron golems. With villagers, a zombie and a golem trap, valuable resources can be farmed permanently.

Functionality

Villagers create an iron golem when they:

  • have access to a bed and a working block

  • Have completed a working day

  • Experience a scare from a nearby zombie

  • The Iron Golem spawns in a defined area near the villagers

  • It is guided into a death zone (e.g. magma blocks or lava) in a controlled manner

  • A funnel system collects the drops: iron ingots and occasionally poppies

Building a simple iron farm

Required components:

  • 3 villagers

  • 1 zombie (in a safe position visible to the villagers)

  • 3 beds

  • 3 work blocks (e.g. composter)

  • Golem killing chamber (magma blocks or lava with funnels underneath)

  • Solid platform for golem spawn (at least 5×5 blocks)

Steps:

  • Build a safe enclosure for villagers with a view of the zombie

  • Position beds and work blocks correctly

  • Make sure villagers can work daily

  • Guide golems to the death zone using water streams or chutes

  • Collect items via funnels into a crate

Increase efficiency

  • Scaling - Place several modules next to each other or on top of each other

  • Keep spawn platform regularly clear of cats (prevent golem spawn)

  • Use name tags or boats to permanently secure zombie

  • Simulate day-night rhythm with daylight sensor or automatic harvest farm

Tips

  • Position the farm high above the ground to avoid spawns outside

  • Test the spawn area with temporary blocks before activating the trap

  • Make sure that golems cannot appear outside the trap

Trivia

  • A working iron farm yields 30-75 iron bars per hour, depending on the design

  • Poppies are also collected by killing golems

  • Iron farms are among the most popular automation projects in Minecraft
