Minecraft Structure Finder

Find every structure in your world. Enter your seed to map villages, strongholds, monuments, mansions, ancient cities, temples and more, each with exact coordinates.

Every structure in your world, on one map

Turn on the structures you care about in the Layers list and the map marks each one it finds, colour-coded by type. Click a marker for its exact chunk and a teleport command. The biome layer underneath shows why each structure sits where it does, since almost every structure type is restricted to a set of biomes.

Use it to plan a route: an ancient city for the deep dark loot, a woodland mansion for totems, an ocean monument for sponges and a village to come home to, all lined up before you leave.

How structure placement works

Minecraft divides the world into square regions measured in chunks, a different size per structure type. Your seed and the region coordinates seed a random number generator that picks a candidate spot inside the region, then the game checks the biome there against the structure's allow-list. Pass and it generates, fail and that region simply has none.

This is why rarity varies so much. Villages use a 34 chunk grid and six common biomes, so they are everywhere. Woodland mansions use an 80 chunk grid and only dark forest, so a world can go tens of thousands of blocks without one.

Frequently asked questions

What structures can this find?
Villages, strongholds, ocean monuments, woodland mansions, ancient cities, trial chambers, desert pyramids, jungle temples, swamp huts, igloos and pillager outposts by default, with ocean ruins, shipwrecks, ruined portals, buried treasure, mineshafts and trail ruins available as extra layers. Tick whichever you want in the Layers list.

How does Minecraft decide where structures go?
For most structures the world is divided into a grid of regions a fixed number of chunks across. Your seed plus the region coordinates feed a random number generator that picks a spot inside that region, and the structure only generates if the biome there is on its allow-list. That is why villages cluster in plains and savanna while mansions are so rare: dark forest is uncommon and the mansion grid is 80 chunks wide.

Why can I not see mineshafts by default?
They are extremely dense and would bury every other marker. Turn the Mineshafts layer on if you want them, ideally with the other layers off. Buried treasure is off by default for the same reason.

Are the coordinates exact?
They give you the chunk each structure generates in, which puts you within about 8 blocks of it. Minecraft decides the fine placement and orientation when the chunk actually loads, so treat the marker as the right chunk rather than the exact block of a doorway.

Does this work for Minecraft Bedrock Edition?
Yes. Use the Java / Bedrock toggle above the map. Be aware the two editions are not interchangeable: since 1.18 they share terrain and biome generation, so the landscape for a given seed looks nearly the same, but structures like villages and strongholds use edition-specific placement and end up in different places. Bedrock also uses 32-bit seeds where Java uses 64-bit.

Is my seed sent to a server?
No. The whole map is computed in your browser with JavaScript. Your seed never leaves your device, there is no account, and no download is necessary.

Can I share a link to what I am looking at?
Yes. The address bar updates as you pan and zoom, so you can copy the URL at any time, or press Copy link. Anyone opening it lands on the same seed at the same position and zoom.

What do the grid lines mean?
The fine grid is chunks (16x16 blocks), which is the unit slime chunks and mob spawning work in. The heavier grid is regions (512x512 blocks, or 32x32 chunks), which is the unit Minecraft uses when deciding where to place structures. Brighter lines through the middle mark the world origin at X=0, Z=0.
