About Woodland Mansion
What the structure is, and what it's worth the trip for
Woodland Mansions are the rarest above-ground structure — typically 10,000+ blocks from spawn. They're the only natural source of Totems of Undying (from Evokers) and the Wild and Ocean banner patterns.
The finder spirals outward up to 12 regions (≈15,000 blocks) — most seeds have a hit inside that range. If not, widen the search by setting a starting position closer to the suspected location.
How it works
The placement rules this finder reproduces
Mansions use an 80-chunk region grid — the largest of any structure — and generate in the Dark Forest and Pale Garden biomes (Pale Garden was added in Java 1.21). Cubiomes' biome validator catches candidate positions in the wrong biome and skips them.
Tips
Getting a useful result on the first search
- Bring an Iron Golem build kit — placing one on the upper floors clears a room of Vexes safely.
- Evokers always drop a Totem of Undying. Wear it in your offhand.
- Mansions can have hidden rooms (allium-decorated, secret chests) — bring a pickaxe for the wool walls.
- The roof is the safest base camp — light it with torches first.
- Use the Nether portal calculator to plan a 1:8 highway after you find one.
Frequently asked questions
What people ask about finding this structure
How do I find a woodland mansion? +
Woodland mansions generate only in the Dark Forest biome on an 80×80-chunk region grid — the rarest large structure in vanilla. Enter a seed above and this finder iterates the placement RNG to return the nearest mansion's (x, z).
How far is a woodland mansion from spawn? +
Because the placement grid is 80 chunks (1280 blocks) and Dark Forest biomes are uncommon, mansions typically land 1500 to 10,000 blocks from spawn. The finder gives the exact distance for your specific seed.
Why can't I find a woodland mansion in my world? +
Mansions spawn in Dark Forest only, on a sparse grid, and biome validation can reject candidates. If your closest result is far, build a Nether portal — every block in the Nether covers 8 in the Overworld, so the trip shrinks 8×.
