Ancient Cities spawn underground in specific biomes and require you to dig down to Y-level −52 or lower

An Ancient City is a generated structure in Minecraft that appears only in the Deep Dark biome, which sits far below the surface. You cannot find one by walking around on the ground — you have to descend into the deep underground, usually by digging a shaft or following a cave system downward. The city itself is a large structure made of deepslate and sculk blocks, filled with loot chests and the dangerous Warden mob.

The fastest way to locate one is to use the seed finder method: look up your world seed online using a tool like Chunkbase or Cubiomes, which will show you the exact coordinates of every Ancient City in your world. If you prefer to find one without tools, you need to descend to Y-level −52 or lower and search the Deep Dark biome by exploring caves or digging.

Key Takeaways

  • Ancient Cities only generate in the Deep Dark biome, which exists only below Y-level −52.
  • Using a seed finder website with your world seed shows you the exact location of every Ancient City without searching.
  • If you search manually, descend into caves or dig a shaft down to Y-level −52, then explore horizontally to find the Deep Dark biome.
  • The Warden mob spawns in Ancient Cities and kills you quickly, so bring healing items and consider sneaking to avoid triggering it.
  • Loot chests in Ancient Cities contain valuable items like enchanted books and diamonds, but you must navigate the structure carefully.

Using a seed finder to locate coordinates when ready

The easiest method is to visit Chunkbase.com or Cubiomes.net, enter your world seed (found in your world settings), and select "Ancient City" from the structure list. Both tools will display a map with red markers showing every Ancient City in your world, along with exact X and Z coordinates. This takes two minutes and removes all guesswork.

To find your seed in Java Edition, open the world in single-player, press F3 to open the debug screen, and look for the line that says "Seed:". Copy that number and paste it into the seed finder. In Bedrock Edition (Windows 10, console, mobile), the seed is shown in the world settings menu under "World" — look for the line labeled "Seed".

Once you have coordinates, use them to navigate. Open your map (press M in Java, or check the map in your inventory in Bedrock), or straightforward write the numbers down and use them as a waypoint. Teleport directly there using the command /tp @s X Y Z if you have cheats enabled, or walk and use a compass to orient yourself.

Descending to Y-level −52 if you prefer manual exploration

If you want to find an Ancient City without a seed finder, you must reach Y-level −52 or lower. In Java Edition, press F3 to see your current Y-coordinate on the left side of the screen. In Bedrock Edition, enable the "Show Coordinates" option in world settings, then look at the coordinates displayed on screen.

The fastest descent is to dig a straight shaft down using a pickaxe. Find a safe location away from mobs, dig down in a 2×2 or 3×3 column, and place torches on one wall so you can find your way back up. Stop when you reach Y-level −52. Alternatively, find a cave entrance and follow it downward — caves naturally descend and often reach the deep levels faster than digging.

Once you reach Y-level −52, you are in the range where the Deep Dark biome can spawn. Explore horizontally by walking through caves or digging tunnels. The Deep Dark biome has a distinctive appearance: the ground is made of deepslate and sculk blocks (which look dark and slightly glowing), and the air feels heavy. When you see these blocks, you are close to an Ancient City.

Recognizing the Deep Dark biome and the Ancient City structure

The Deep Dark biome looks different from other underground areas. The blocks are primarily deepslate (dark gray) and sculk (dark with a faint blue-green glow). Sculk blocks are the key identifier — they do not appear in other biomes. You may also see sculk sensors (which detect vibrations) and sculk shriekers (which spawn the Warden).

The Ancient City itself is a large structure made of deepslate bricks, deepslate tiles, and sculk blocks arranged in a geometric pattern. It contains multiple rooms, corridors, and chambers. You will see loot chests, candles, and various decorative blocks. The structure is not small — it can span hundreds of blocks in each direction, so you may enter it without realizing it at first.

The most dangerous part of an Ancient City is the Warden. This mob is invisible until you trigger it by making vibrations (walking, jumping, breaking blocks, or hitting sculk shriekers). Once triggered, it hunts you relentlessly and deals massive damage. Avoid triggering sculk shriekers, and consider sneaking (hold Shift in Java, hold the sneak button in Bedrock) to move silently.

Gathering loot safely without triggering the Warden

Ancient Cities contain valuable loot in chests scattered throughout the structure. Common items include enchanted books, diamonds, emeralds, and unique items like the recovery compass. To collect loot without dying, move slowly and carefully — use sneaking to avoid vibrations that trigger the Warden.

Bring healing items: food (cooked meat or bread), healing potions, and milk buckets. Milk buckets are especially useful because they remove the "Darkness" effect that the Warden applies, which makes it harder to see. If you trigger the Warden and cannot escape, drink milk and run toward the surface as fast as possible.

A safer strategy is to use a ranged weapon like a bow or crossbow to break chests from a distance, then collect the items after the Warden loses interest. You can also place blocks to create barriers between yourself and the Warden while you loot. Some players bring beds and use them to create explosions that damage the Warden, though this is risky and requires practice.

Preparing your inventory and equipment before entering

Before you enter an Ancient City, equip yourself properly. Wear full diamond or netherite armor (netherite is better because it is more durable). Bring a pickaxe to mine blocks if needed, a sword for combat, and a bow with arrows. Pack healing items: at least 20 food items, several healing potions, and 2 to 3 milk buckets.

Bring a water bucket to prevent fall damage if you accidentally drop into a pit. Bring a stack of torches or another light source so you can see clearly — the Deep Dark is dark even with torches. Consider bringing an ender pearl or two so you can teleport away quickly if the Warden appears.

Leave a clear path back to the surface. If you descended via a shaft, mark it with torches or a distinctive block so you can find it again. If you used a cave, place torches along the walls as you explore so you can retrace your steps. Do not venture too far from your exit point on your first visit.

Frequently Asked Questions

Can I find an Ancient City in Creative mode?

Yes. In Creative mode, you can fly down to Y-level −52 and search for the Deep Dark biome, or use the seed finder method to get exact coordinates. You can also use the /locate command to find the nearest Ancient City: type /locate structure ancient_city and the game will show you the coordinates.

What happens if the Warden kills me?

You drop all your items at the location where you died, and you respawn at your spawn point (usually your bed or the world spawn). You have five minutes to return to your death location and collect your items before they disappear. If you died far underground, bring a new set of tools and retrace your steps.

Do Ancient Cities exist in Bedrock Edition?

Yes, Ancient Cities generate in Bedrock Edition on all platforms (Windows, console, mobile) in the same way as Java Edition. The seed finder tools work for Bedrock seeds as well. The structure and loot are identical.

Is there a command to teleport directly to an Ancient City?

In Java Edition with cheats enabled, use /locate structure ancient_city to find the nearest one, then use /tp @s X Y Z to teleport to those coordinates. In Bedrock Edition, the /locate command works the same way. You must have cheats enabled in your world settings.

Can I disable the Warden so I can explore safely?

In Creative mode, you are invulnerable and the Warden cannot hurt you. In Survival mode, you cannot disable the Warden, but you can avoid triggering it by sneaking and not hitting sculk shriekers. Some players use commands to remove the Warden after triggering it, but this requires cheats enabled.
