Ancient City

An ancient city is a palatial structure found in the deep dark, harboring chests containing items that cannot be found anywhere else or that help a player avoid a warden.

Environment aesthetics
An ancient city features a very large palace that stretches throughout a deep dark biome. The palace is made up of long corridors with gray wool floors to prevent vibrations as well as some smaller ruins off to the side of the main corridors, which contain between one or two loot chests. The city center features a frame resembling a warden's head, where there are reinforced deepslate blocks, which is an unobtainable material in Survival mode. Other unique blocks such as soul lanterns and candles as well as different forms of deepslate can be found here.

Blocks
An ancient city is the only place in the Overworld where soul sand, soul soil and polished basalt can generate naturally. It is also the only place in the game where a skeleton skull can generate naturally.

Loot
The loot in the chests includes several useful items for exploring the ancient city, such as snowballs and the Swift Sneak enchantment.

Trivia

 * Some statues scattered throughout the ancient cities bear a resemblance to early iterations of the warden's design.
