Ancient City structure in Minecraft

How to find an Ancient City

Ancient Cities only generate in the Deep Dark, the sculk-covered cave biome that usually lies under mountains. The game allows at most one city per region of 24 × 24 chunks, never closer than 8 chunks to the next one, and many regions have none because they contain no Deep Dark. The city is built around Y -51 and can stretch over more than 200 blocks.

Use the /locate command shown above or the seed map, then dig a staircase down to the edge of the city rather than straight into it. Sculk already carpets the caves around it: as soon as you see it, behave as if you were inside.

Sculk sensors, shriekers and the warning level

Nothing spawns naturally inside an Ancient City: no zombies, no skeletons, no creepers. The danger is sculk. Sculk Sensors pick up vibrations: footsteps, landings, blocks placed or broken, projectiles hitting something, chests being opened. A Sculk Shrieker goes off when a nearby sensor fires or when you step on it. Each shriek gives you Darkness and raises a hidden warning level, and the fourth one summons the Warden, which digs its way out of the ground nearby. The level slowly goes back down if you stay quiet.

Only the shriekers placed by world generation in the city can summon a Warden. Those that grow later around a Sculk Catalyst still shriek and give Darkness, but never call it.

How to deal with the Warden

The Warden is blind. It follows vibrations, sniffs out what it cannot hear, and grows angrier each time it detects you. With 500 health, crushing melee hits that also disable shields, and a ranged sonic boom when it cannot reach you, it is not meant to be fought. Back away quietly instead: if it detects nothing for 60 seconds, it digs back underground.

To lure it away from a chest, throw a Snowball, an egg or an arrow far from where you stand: the impact makes a vibration it goes to check. Don't throw several in a row, or it works out where they come from.

How to move without being heard

• Sneak all the time. Crouched footsteps make no vibration. Never step on a sensor or a shrieker, even crouched: stepping on one always sets it off.
• Use wool. Walking on wool or carpet is silent, placing or breaking them makes no vibration, and a wool block between you and a sensor blocks the signal. The city's floors already contain plenty of gray wool and carpet.
• Disarm before you loot. Wall off the sensors around a chest with wool, which is silent, or break them with a hoe, the fastest tool on every sculk block.
• Get Swift Sneak. Once you find a book, put it on your leggings: it raises your speed while crouched, up to level III.

What's worth looting

Chests are the reason to come. They are the only place to find Swift Sneak books, which no librarian sells. They also hold enchanted books that can carry Mending, enchanted diamond leggings, enchanted golden apples, Bottles o' Enchanting, the Ward Armor Trim and, more rarely, the Silence Armor Trim. Collect every Echo Shard: eight around a compass make a Recovery Compass, which points to where you last died. Nine Disc Fragments craft the music disc "5", and the chests can also hold otherside, 13 and cat.

Some cities also have an icy storeroom. Its chest is filled with packed ice, snowballs, golden carrots, baked potatoes and suspicious stew.

Candles, soul lanterns and the central portal

The streets are lit only by candles, soul lanterns and blue soul fire, so light levels stay low. At the heart of the city stands a huge portal-shaped frame of Reinforced Deepslate. It leads nowhere, and its blocks cannot be obtained in Survival, but it makes a perfect landmark: if you get lost, head toward it, then retrace your steps from there.
