About these 1.18 seeds

Woodland mansions are among the rarest structures in the game — in a typical world the nearest one is many thousands of blocks away, which is why the game sells you a map to find it. Every seed on this page has a mansion within 1,200 blocks of spawn, with the exact coordinates on the card.

1.18 (Caves & Cliffs Part II) rewrote terrain generation completely: world height stretched to Y −64…319, six new mountain biomes, and cave systems bigger than anything before it. It's also where modern seeds begin — a 1.17 seed generates a totally different world — and 1.18.2 is still a heavily-played modpack version. Every seed below was verified on 1.18 generation itself.

Verified for Java Edition 1.18 (Caves & Cliffs Part II). Biomes, terrain and structure locations are identical across 1.18 – 1.18.2, so 1.18.2 modpack worlds match these maps.

For the current Java 26.3 release, see the main mansion seeds — or the same list for 26.3 · 1.21.4 · 1.20 · 1.19 · 1.16. All 1.18 lists live under best 1.18 seeds.

Frequently asked questions

How is this different from the main mansion seeds page?
These seeds are computed for Java 1.18. The main mansion seeds list targets Java 26.3. Match the version on the card; older versions can generate different biomes and structure positions.
Which releases do these seeds work on?
The whole 1.18 line — 1.18 through 1.18.2, including 1.18.2 modpacks: biomes, terrain and structure positions are identical across the patches (1.18.2 only fixed cosmetic generation bugs like underwater snow patches). Later versions keep the same terrain engine but add structures and tweak placements (1.19's ancient cities, 1.20's trail ruins), so verify on our newer lists if you're playing past 1.18.
Do these seeds work on Bedrock Edition?
No — Java and Bedrock generate different worlds from the same seed. These lists are Java Edition only.
