Build a gatehouse with a gate that slams shut and opens again on command.
A wall with a hole in it is just a fence. Build a castle gate that slams shut with one flick of a lever.
- New skill Building a working piston gate
- Level 2 · Rise of the Kingdom
- Difficulty Beginner
- Mode Survival
- Time 35–45 min
- Ages 13+
What you’ll build
Sketch a gatehouse and compare the cost of an iron door with a piston gate. Hide pistons in the walls facing the gap so they slam it shut when powered, then wire and test each one. Build the gatehouse around the machinery and run a siege test.
Finish line: Your gatehouse has a hidden piston gate that slams fully shut and opens again on command.
Bonus challenge: Flip it: add a NOT gate (Mission 143) so lever ON means gate OPEN. Then dare someone to work out how to get in.
You’ll need
- Pistons
- Redstone
- A lever
- Cobblestone and planks
- Iron ingots
You choose
- Gate type (iron doors or pistons)
- Gate width (1 or 2 blocks)
- Secret hiding spot for the lever
Stuck?
- Power each piston directly with dust, a lever or a torch beside it. It's the most reliable way.
- Test every piston on its own before wiring them together.
- Redstone dust needs a solid block under it, so check none of it is floating.
