Minecraft Ancient City Finder
Find every Ancient City on your Minecraft seed — Java 26.2 & Bedrock 1.26.40, any seed, free, no sign-up.
Quick answer: Ancient Cities generate deep underground in the Deep Dark biome, around Y ‒51, only in the Overworld — rare and dangerous. This finder locates them at 97% accuracy on Java and 91% on Bedrock.
Where do Ancient Cities spawn?
Ancient Cities spawn only in the Deep Dark biome, deep underground around Y ‒51 in the Overworld. The Deep Dark forms beneath mountainous terrain, so cities sit far below the surface — you usually dig down or follow a cave system to reach one.
How do I find an Ancient City in my seed?
Enter your seed and the finder marks every Ancient City. Open a marker for its coordinates, then tunnel down to roughly Y ‒51 at that X/Z. Approach carefully — setting off sculk shriekers can summon the Warden.
How rare is an Ancient City, and why isn’t the accuracy 99%?
They are rare — a typical world has only a handful within a few thousand blocks of spawn. The Deep Dark’s terrain is harder to predict than a surface structure, which is why the published figure is 97% on Java and 91% on Bedrock rather than near-exact.
Does the finder work on Bedrock? What version added Ancient Cities?
Yes — both editions, Minecraft 26.2 (Java) and 1.26.40 (Bedrock). Ancient Cities were added in 1.19 on both. Markers read 97% on Java and 91% on Bedrock.
What Y level is the Ancient City?
Ancient Cities sit deep — the floor of the city generates around Y minus 51, and the structure reaches up from there, so Y minus 52 to minus 40 is the band you want to be tunnelling at. That depth is not a coincidence: cities only generate in the Deep Dark, which itself only forms in the lowest cave layer under high surface terrain. If you are digging under a mountain range and the stone turns to sculk, you are at the right depth already. Read the coordinates off a marker above and dig straight down at that X/Z — but light your way out, because a sculk shrieker triggered four times summons the Warden.
