Ancient City
An enormous ruined complex in the Deep Dark, where sculk sensors and shriekers punish careless exploring. Its chests hold echo shards, Swift Sneak books, disc fragments, and sought-after armor trim templates.

How it generates
Generates deep underground with its main floor at Y=-51. The Deep Dark biome it needs goes with low-erosion terrain, often under mountains and plateaus.
Biomes
- Deep Dark
Placement values are for Java 26.3, in chunks. A candidate only becomes a city if the Deep Dark is there. In Java the structure's starting anchor is Y=-27, which differs from the main floor height. Mobs don't spawn naturally inside a Java city, but its shriekers can summon wardens. Bedrock's exact placement values aren't confirmed.
