An ancient city is a palatial structure found in deep dark biomes at Y=-51, that harbors chests containing items, such as disc fragments, armor trims, and echo shards, that cannot be found anywhere else. It is also one of the only two places where sculk can be found.

Generation

[edit | edit source]

Ancient cities cannot generate overlapping each other; however, they can generate directly adjacent to each other.[1]

Because they can only generate in the deep dark, they will often be found under mountains and other places with low erosion.

Ancient cities can be located with "buried ancient city" explorer maps, which are found in secret chests in abandoned camps.

Structure

[edit | edit source]
For the technical details behind ancient city structures, see Ancient City/Structure. For the blueprints of ancient city structures, see Ancient City/Structure/Blueprints.

Environment aesthetics

[edit | edit source]

An ancient city features a massive palace with a footprint of around 220 blocks on each horizontal axis, stretching throughout a deep dark biome. The floor of the city always generates at Y=-51 and is about 20 blocks high. The palace is made up of long corridors with 2-block-deep floors of gray wool, with the occasional rugs of blue, light blue, and cyan wool or carpet floors to reduce vibrations. Off to the sides of the main corridors are smaller ruin structures, which often contain one or two loot chests. The city's center features a frame resembling a portal that contains exclusive reinforced deepslate blocks, though these are unobtainable in Survival mode. Other unique blocks such as soul lanterns, candles, and different forms of deepslate and sculk can be found throughout the city. Sculk shriekers generate much more frequently in ancient cities than in the normal deep dark biome. The city always generates at the same position within a chunk (for example, the blocks that make up the center frame structure are always on the western edge of a chunk).

Some of the city's structures resemble other elements of the game. The city center bears a resemblance to early iterations of the warden's design, and other structures are similar in appearance to pillager outposts, the wool rooms in woodland mansions, and abandoned mineshafts.

Overall view

[edit | edit source]

The following three renders are of the same individual ancient city.

Redstone circuits

[edit | edit source]

Underneath the portal of the city center lies a series of hidden basement rooms with naturally generating redstone circuitry.

The secret entrance is located at the base of the structure, underneath the wooden bridge between the city center and the wall. There is a piston door that is controlled by a sculk sensor in the basement's redstone circuits.

For city_center_1, there is a chiseled deepslate block in front of the frame. Making a vibration around it can activate the sculk sensor and then open the piston door. There is also a pulse extender between the sculk sensor and piston door, which makes the piston door close 180 game ticks after the sculk sensor is deactivated.

The circuit in city_center_2 is similar to the former, but with a signal strength filter. Only vibrations with a frequency equal to 8 (eating or drinking) can activate the piston door. Creating these vibrations on the path in the front of the frame in the city center activates the door.

For city_center_3, making a vibration on the path in front of the frame on the city center can activate the sculk sensor. Additionally, there is a T flip-flop between the sculk sensor and piston door. After the sculk sensor is activated, the piston door remains open until the sculk sensor is activated again.

There are three basic redstone circuits in the basement:

See also: Chest loot

The loot in the chests includes several useful items for exploring the ancient city, such as snowballs and the Swift Sneak enchantment, as well as items that cannot be found anywhere else, such as echo shards and two exclusive armor trims. Ancient city chests also have the second highest chance of any loot table to contain an enchanted golden apple—ominous vaults have a 22.5% chance.

  1. ↑ 'Nothing' does not refer to the chance of an empty chest. Instead, it refers to the chance that the random loot generator does not add any loot on a single roll.
  2. ↑ All enchantments are equally probable, including treasure enchantments (except Soul Speed, Swift Sneak, and Wind Burst), and any level of the enchantment is equally probable.
  3. ↑ Enchanted with a random level of Swift Sneak.
  4. ↑ Enchantment probabilities are the same as a level-20 to level-39 enchantment would be on an enchanting table that had no cap at level 30, and that was able to apply treasure enchantments (except Soul Speed, Swift Sneak, and Wind Burst), and where the chance of multiple enchantments is not reduced.

  6. ↑ The item has between 80% and 100% of its total durability.

Trivia

[edit | edit source]
  • In some concept art, it was revealed that the loot in ancient cities was originally going to be stored within jar-shaped pots, "screaming" vases, and stone chests.[2]
  • The intention of the ancient cities was to capture a feeling of something that feels like it was once bustling with life, but is now vacant and lifeless.[3]
