Quick answer: Ancient Cities generate in the Deep Dark biome, which forms deep underground (around Y=-51) beneath mountains and other high-erosion terrain. To find one, dig down to the lowest levels and look for sculk blocks, or use /locate structure minecraft:ancient_city. Tread carefully — the Deep Dark is home to the Warden.
Ancient Cities are the most dangerous — and most rewarding — structures in Minecraft. They hold loot found nowhere else, guarded by sculk sensors and the terrifying Warden. Here’s how to find one and survive.
Where Ancient Cities Generate
- Biome: only in the Deep Dark, a cave biome full of sculk blocks that generates deep underground.
- Depth: Ancient Cities sit around Y=-51, near the bottom of the world (the world floor is Y=-64).
- Location: the Deep Dark forms beneath mountains and other terrain with low erosion, so digging down under a mountain range is your best bet.
How to Find One
- Dig down under mountains. Head to a mountainous area and dig or cave your way toward Y=-51. When you start seeing sculk veins and sculk blocks, you’re in a Deep Dark.
- Follow the sculk. The more sculk you see, the closer you are. Ancient Cities are large deepslate structures buried in the Deep Dark.
- Use the locate command. With cheats on,
/locate structure minecraft:ancient_citygives you the nearest city’s coordinates. See our commands list. - Or use a seed. An ancient city seed can put one right near spawn.
The Danger: Sculk and the Warden
The Deep Dark is built around sculk sensors and sculk shriekers that detect vibrations. Sprinting, breaking blocks, and fighting all make noise. Trigger a shrieker enough times and it summons the Warden — a blind, massively powerful mob that hunts by sound and smell and can kill a fully-armoured player in two hits. You cannot realistically fight it; the goal is to stay quiet and avoid it.
- Crouch (sneak) to move without triggering sensors.
- Place wool over sculk sensors and shriekers to muffle vibrations.
- Bring a silk touch pickaxe to remove shriekers safely, and don’t sprint or fight near them.
The Loot
Ancient City chests hold gear you can’t get anywhere else, including:
- Swift Sneak — a leggings-only enchantment that lets you crouch-walk at nearly full speed (only found here).
- Echo Shards — used to craft the Recovery Compass, which points to your last death location.
- Disc Fragments — craft into the music disc “5”, plus enchanted diamond gear and other rare loot.

FAQ
What Y level are Ancient Cities on?
Ancient Cities generate around Y=-51, deep in the Deep Dark biome near the bottom of the world.
Can you kill the Warden?
Technically yes, but it has so much health and hits so hard that it’s not practical — the intended strategy is to avoid it by staying quiet and sneaking. Muffle sculk sensors with wool and don’t trigger shriekers.
