【Minecraft】How to Use the Bastion Remnant Finder (Piglin Bastion Finder) Tool With Real Examples【Java / Bedrock】

This guide is for players who want to pinpoint Piglin bastions (Bastion Remnants) in the Nether.
We’ll walk through how to use the external tool “Bastion Remnant Finder” (Piglin Bastion Finder).
The steps work for both Java Edition and Bedrock Edition.

Hey there, I’m Yuzukaki.

“I want Netherite Upgrade Smithing Templates, but I just cannot find a Piglin bastion…”
“I want to trade with Piglins, but where on earth is a bastion…?”

If you’ve been progressing through the Nether, you’ve probably run into this kind of problem at least once.

A Piglin bastion generated jutting out into the Nether lava sea

Piglin bastions do generate all over the Nether, but because of biome and structure rules, finding them can feel like pure luck, so “I walked forever and still didn’t find one” happens a lot.

So this time, we’ll go through how to use the external tool “Bastion Remnant Finder” (which I’ll call the Piglin Bastion Finder in this article) to locate Piglin bastions step by step.

After reading this article, you’ll be able to:

Accurately locate Piglin bastions in your own world
Understand how to use the tool for both Java and Bedrock
Get rid of that “I don’t really get what this Piglin Bastion Finder screen means…” feeling
And as a bonus, keep a checklist for when the bastion isn’t there even though you followed the coordinates

If this helps even a little with your Nether life, I’ll be happy.

This guide uses Chunk Base’s “Bastion Remnant Finder” as the example tool.
This guide assumes Minecraft Java 1.21.x and Bedrock 1.21.x.

If you just want “How do I use the Piglin Bastion Finder?” you can jump straight to Section 4 and you’ll be fine!

1. What Is a Piglin Bastion (Bastion Remnant)? Basic Mechanics and Spawn Conditions

First, let’s quickly break down what a Piglin bastion (Bastion Remnant) actually is.
If you know this part, it becomes much easier to understand what the finder is showing you.

1-1. What exactly is a Piglin bastion?

Visually, it looks something like this:

The full view of a gigantic Piglin bastion

The official name is “Bastion Remnant”, and:

A huge structure made mainly of blackstone that generates in the Nether
Inhabited by Piglins, Piglin Brutes, and Hoglins
From the chests you can get things like:
- Netherite Upgrade Smithing Template
- Gold blocks, ingots, and gold gear
- The music disc “Pigstep” and the “Snout” banner pattern, etc.

…in other words, it’s basically a treasure vault for late-Nether gear upgrades, gold resources, and decorative items.

1-2. Which biomes can they spawn in?

Piglin bastions:

Can spawn in every Nether biome, but
The “Basalt Deltas” biome is the one exception where they don’t spawn

Sometimes part of a bastion can stick across the border into a Basalt Deltas, but if the structure would generate in Basalt Deltas, it won’t generate there.

So basically:
If you’re wandering around inside Basalt Deltas, you won’t find a bastion that spawns there.
That’s the key point.

1-3. Relationship with Nether fortresses (they “compete” in the same region)

Piglin bastions and Nether fortresses have a special generation rule:

The Nether is divided into “regions”: 432×432 blocks in Java / 480×480 blocks in Bedrock
For each region:
- Either a Bastion Remnant or a Nether fortress can generate
- Biome restrictions can also cause neither to generate in that region

Region? generation? …what does that even mean in practice?

To put it simply:

A Piglin bastion will not generate right next to a Nether fortress inside the same region.

So if you’re in an area that keeps giving you fortresses, you can end up in a stretch where bastions feel weirdly scarce.

2. What Is the Piglin Bastion Finder (Bastion Remnant Finder)?

Here I’ll quickly explain what the Piglin Bastion Finder is.

2-1. What can this tool do?

In this article, we’ll be using the web app Chunk Base “Bastion Remnant Finder.”
(Just search that name and you’ll find it instantly.)

What this tool does is:

You enter your world’s seed value
Choose your edition and version (Java or Bedrock, and the right version range)
Enter your current Nether coordinates (X/Z)

And then it:

Shows you a map with Bastion Remnant locations and their coordinates, centered around where you are.

2-2. Supported versions

Chunk Base’s Bastion Remnant Finder supports both Java and Bedrock, including older Nether Update-era versions and the current 1.21 releases.
The dropdown is fairly detailed (it’s split into version ranges), so the safest move is:

Pick the exact edition and version range you’re actually playing—especially on older or updated worlds.

2-3. Strengths and “little things to keep in mind”

◎ Strengths

You don’t have to wander around the Nether blindly; you can see at a glance which direction to head
The same general workflow works for both Java and Bedrock
When you click a bastion marker, the tool can show which variant it is (Treasure Room / Bridges / Hoglin Stables / Housing Units)

It’s honestly awesome that it even shows you the bastion variant.

△ Things to be aware of

Functionally, it’s a “spoiler” for exploration—if you love going in blind, it might not be your style
It’s so convenient that you may start outsourcing everything to tools
→ I’d recommend drawing your own line like “Nether only” or “Only for utility worlds,” etc.

3. Prep: How to Check Your Seed Value and Nether Coordinates [Java / Bedrock]

Before you can use the Piglin Bastion Finder, you’ll need two things:

Your world’s seed value
Your current Nether coordinates (X/Z)

This section shows how to check those in both Java and Bedrock.

3-1. Java Edition: how to get your seed

For Java single-player worlds, this is super easy.

Enter the world you want to use (Overworld or Nether, either is fine)
Press the T key to open chat
Type /seed and press Enter
The number displayed in chat is your world’s seed

If you run the command above, your seed shows up like this (Java).

For multiplayer servers:

Whether /seed is allowed depends on the server settings
You might also need the right permissions (operator/OP)

If it doesn’t show, you’ll need to ask the server admin for the seed.

When dealing with seeds on multiplayer, make sure you’re not breaking any local rules—always check first.

3-2. Bedrock Edition: how to get your seed

In Bedrock Edition (Switch / PlayStation / mobile / Windows, etc.), you usually check the world settings menu.

Join the world you want to check
Open the pause menu, go to Settings → Game
Scroll down; there’s a Seed field showing a number

👆 The red-circled number here is the seed (Bedrock).

If you don’t have access to the world settings (common on servers/Realms), you’ll need to ask the owner/admin for the seed.

3-3. How to see your Nether coordinates (X/Z)

Java Edition

Press F3 to open the debug screen
On the left side you’ll see something like: XYZ: 100.123 / 64.000 / -200.987
Here:
- X: east–west
- Z: north–south
While you’re in the Nether, jot down those X and Z values

Press F3 and the red-underlined numbers here are your coordinates (Java).

Bedrock Edition

Go to Settings → Game → turn on Show Coordinates
On the top-left of the screen you’ll see something like Position: 100, 64, -200
Again, note the X and Z values

👆 Turn on the red-circled “Show Coordinates” in Settings → Game (Bedrock).

You’re good once the coordinates show up in the top-left!

Make sure you’re recording your Nether coordinates here.
The scale is different from the Overworld (1 block in the Nether = 8 blocks in the Overworld), so don’t mix them up.

4. Basic Usage of the Piglin Bastion Finder (PC / Mobile)

Now let’s go through how to actually operate the Piglin Bastion Finder screen.
Open the tool in your browser and follow along.

4-1. Quick tour of the screen layout

The Piglin Bastion Finder screen is roughly laid out like this:

Top:
- Seed (where you enter your seed)
- Version (select edition + version range)
Center:
- A Nether map with Bastion Remnant locations shown as markers
Bottom:
- X / Z coordinate input fields + a Go! button
- A Grid Lines checkbox (to show a grid overlay)

On the map:

The pin in the center = your current location (the X/Z you entered)
The markers around you = Bastion Remnants (Piglin bastions)
If you click/tap a marker, the tool shows details like coordinates and bastion variant.

4-2. Step 1: enter your Seed

First, type in the seed you looked up earlier.

Click the Seed field at the top
Paste or type your seed value from Java or Bedrock
Double-check you didn’t mistype any digits or the minus sign

The Piglin Bastion Finder also accepts “word seeds,” and converts them the same way Minecraft does when creating a new world.

4-3. Step 2: match the Version / Edition

Next, match the edition and version range to what you’re playing.

For Java Edition → choose the Java version range you’re on (for example, a 1.21 range)
For Bedrock Edition → choose the Bedrock version range you’re on (for example, a 1.21 range)

If you get this wrong, the bastion positions can be way off, so this part matters.

If you’ve been playing the same world since older versions and only later updated, set the Version according to which version originally generated the chunks you’re searching (more on that in Section 6).

4-4. Step 3: enter your Nether X/Z and click “Go!”

Once your Seed and Version are set, the map will populate with bastion markers.

From here, to focus on bastions near you, we’ll use the X/Z fields to move the map.

Go into the Nether in-game and note your current position (X/Z)
In the finder, enter those values in the X and Z fields at the bottom
Click Go!

Now:

The map centers on your Nether coordinates, and you can instantly see bastions around you.

4-5. Step 4: pick a nearby Piglin bastion and read its coordinates

The center pin is your current location, so:

Choose one bastion marker that’s reasonably close
Click/tap it to see the bastion’s coordinates (X/Z) and its variant

The tool doesn’t show the Y-coordinate (height), so when you actually go there, you’ll have to look around:

It might be buried inside netherrack
Floating against a cliff
Sitting over a lava sea

…so you’ll search the area while adjusting your height.

4-6. Step 5: make it easier to read with Grid Lines (optional)

If you check the Grid Lines box, a grid appears on the map, which can make distances easier to judge.

This is handy when you’re thinking about:

Rough spacing between structures
Planning a “clear out this whole area” route

5. Example: How to Actually Reach a Piglin Bastion Found with the Finder

Now let’s walk through:

How to actually get to a Piglin bastion whose coordinates you found with the Piglin Bastion Finder.

Here I’ll focus on practical “how to follow the coordinates” rather than detailed combat/raiding inside the bastion itself.

5-1. First, pick one nearby Piglin bastion as your target

The map will show multiple bastions, but for your first one, I recommend picking a spot that:

Isn’t too close or too far from your Nether portal
Is not sitting squarely inside Basalt Deltas
Ideally isn’t smack in the middle of a lava ocean, and looks reachable mostly by land

Pick one that’s within walking distance of your Nether portal if possible.

5-2. Prep for the Nether (gear and items)

Before heading out to the bastion, get some basic gear ready.

Example gear set for going to look for a Piglin bastion

One piece of gold armor (helmet or boots)
- So regular Piglins don’t instantly aggro you
Decent armor and weapons
A bow or crossbow (for ranged attacks)
Plenty of blocks (cobblestone, blackstone, etc.)
- For bridging and making paths
Fire Resistance potions (highly recommended if you have them)
Night Vision potions (nice-to-have for darker areas)

Piglin Brutes ignore gold armor and will attack you anyway, so wearing gold doesn’t make you completely safe.

5-3. A simple way to follow coordinates (match X first, then Z)

When you’re moving toward the target X, Z from the tool, a simple method is:

Match the X-coordinate first
- Example: if you’re at X=0 and aiming for X=400 → dig a straight tunnel or build a straight bridge along the X-axis
Once X matches, then adjust your Z-coordinate

Doing it one axis at a time like this makes it much harder to get lost.

Stick to one axis at a time ← easier not to get turned around.

Since Nether terrain is messy:

You might end up mid-cliff
Inside a wall of netherrack
Directly above a lava ocean

So even if your coordinates match, you may not see the bastion right away.
In those cases, gently adjust your Y-level while looking around for that big, dark, fortress-like silhouette.

The dark outline of a Piglin bastion is pretty recognizable from a distance.

5-4. How to search for the bastion’s “height”

The Piglin Bastion Finder gives you only X/Z, not Y.

If you arrive at the coordinates and still don’t see it:

Dig up and down around that coordinate range
Hollow out a bit of netherrack wall and look through
Check both above and below nearby cliffs

Basically, scan vertically around the target spot while looking for blackstone structures.

Dig up and down near the coordinates, looking for a mass of blackstone.

5-5. Once you find the Piglin bastion, note down its coordinates

After you finally find a Piglin bastion:

Record the entrance coordinates (X/Y/Z) with a sign or screenshot
If you can, set up a Nether portal nearby as an emergency escape route

You really want an emergency escape route from the Nether if things go bad.

6. Tips and Gotchas for Bedrock Edition

From here, I’ll highlight Bedrock-specific differences and points to watch out for.

6-1. The generation algorithm differs between editions, but the tool handles it

Under the hood, structure generation differs between Java and Bedrock.
Chunk Base accounts for this by splitting Java and Bedrock into separate version options—so:

Just make sure you selected the Bedrock version range, and you’re good.

6-2. “Mixed-version” chunks (this matters a lot)

If you:

Started your world on an older version
Then updated later
And you’re searching an area where chunks were generated across different versions

…you have to think:

“Which version first generated these Nether chunks?”

Then pick the Version in the tool to match that.

Also, remember: structures don’t magically appear in chunks that were already generated before that structure existed (or before major generation changes). If something feels “missing,” this is often why.

6-3. Simulation distance doesn’t change whether a bastion exists

Bedrock has “simulation distance,” which affects things like:

Mob behavior
Block updates

But once a chunk is generated, simulation distance doesn’t decide whether a bastion exists there.
So if the finder says a bastion is in that area, focus on seed/version/coordinates and the checklist in Section 8.

6-4. No built-in “chunk border” display in Bedrock

Bedrock doesn’t have anything like Java’s F3+G chunk border display.

The Piglin Bastion Finder works with coordinates, so as long as you know the coordinates, you don’t actually need chunk borders.

If you still want a rough chunk grid for building:

Place marker blocks every 16 blocks
Or use a separate chunk-visualizing add-on/app

7. How to Find Piglin Bastions Without Any Tools

If you’re thinking:

“Tools are useful, but I’d rather not rely on external websites…”

then here are some rough no-tool methods you can try.

7-1. Move in long, straight lines while keeping “regions” in mind

Nether fortresses and Piglin bastions are, under the hood:

Java: region-based spacing tied to 432×432 blocks
Bedrock: region-based spacing tied to 480×480 blocks

Because a region can generate either a fortress or a bastion, you can loosely do this:

From your Nether portal, walk a few hundred blocks in a straight line along X
Turn 90 degrees and walk a few hundred blocks along Z
If you still haven’t found anything, go another few hundred blocks to try crossing into a different region

So the idea is: move hundreds of blocks at a time in straight lines → then turn.

7-2. Tunnel high up and scout

Another approach is digging safer tunnels and scouting from controlled openings.

Carve a straight tunnel along X or Z
At intervals, open side holes to peek outside and scan for blackstone structures

Piglin bastions often have big silhouettes and bridges, so having a clear sightline helps.

7-3. Use biome/structure “patterns” to your advantage

As mentioned earlier:

Bastions don’t generate in Basalt Deltas
Bastions and fortresses share the same regional “slot”

So if you’re seeing fortresses repeatedly, it can be smart to:

Change direction instead of extending the same route forever

7-4. Use the `/locate` command (if you’re okay with cheats)

If you’re in a single-player world with cheats enabled, or in a creative test world, you can use /locate.

Java Edition example:

/locate structure minecraft:bastion_remnant

Bedrock Edition example:

/locate structure bastion_remnant

Just keep in mind:

In Bedrock, enabling cheats can disable achievements for that world
On servers, you’ll need the appropriate permissions

So use it in whatever way fits your own rules and playstyle.

8. Checklist for When the Bastion Isn’t There Even Though You Went to the Coordinates

Sometimes you’ll have a moment of:

“I went to the coordinates from the Piglin Bastion Finder, but there’s no bastion here at all…”

When that happens, go through this checklist from the top:

[ ] Is the Seed really correct? (Even one digit off = completely different world)
[ ] Did you pick the correct Version (Java vs Bedrock + the right version range)?
[ ] If you’ve been playing since older versions: Were those Nether chunks first generated in a different version? (Try switching the Version option accordingly.)
[ ] Are the X / Z coordinates you entered Nether coordinates? (Make sure you didn’t plug in Overworld numbers.)
[ ] Did you search thoroughly above and below around the target spot? (The tool doesn’t give you Y.)
[ ] Is the target area inside Basalt Deltas? → Bastions don’t generate there.
[ ] Is there already a Nether fortress in that same region? → A region won’t generate both a fortress and a bastion.
[ ] Are you using any add-ons, mods, behavior packs, or datapacks that change world generation? (The tool assumes vanilla generation.)
[ ] If it’s a server/Realm: is the seed you entered actually the seed of that world?

If you still can’t find it:

Use the Piglin Bastion Finder again and pick another bastion marker
Double-check that your travel in the Nether isn’t wildly detouring away from the direct route

Basically, debug from both sides: tool settings and in-game movement. Annoying, yeah—but it usually reveals the mismatch fast.

9. Summary

In this article we covered:

How to use the Piglin Bastion Finder (Bastion Remnant Finder) to accurately locate Bastion Remnants.

with both Java and Bedrock players in mind.

Let’s recap the key points:

Bastion Remnants (Piglin bastions):
- Can spawn in any Nether biome except Basalt Deltas
- Share the same region-based “slot” with Nether fortresses—regions generate either a fortress or a bastion, or sometimes nothing
In the Piglin Bastion Finder, entering:
- Your seed value
- Edition + version range (Java / Bedrock)
- Your current Nether X/Z coordinates
lets you quickly map out Piglin bastions in your world.
In Java Edition, you can use /seed and F3 to get your seed and coordinates.
In Bedrock Edition, check the seed in world settings and track your destination by coordinates.
If you still can’t find the bastion even after following the tool:
- Double-check Seed / Version mistakes
- Make sure you didn’t mix up Nether and Overworld coordinates
- Watch out for Basalt Deltas and mixed-version chunks, using the checklist

Found a Piglin bastion at last! And then…

Once you’ve secured a Piglin bastion, things like:

Upgrading to Netherite gear (Netherite Upgrade Smithing Templates)
Stocking up on rare items
Farming big amounts of gold blocks and ingots

all become way easier.

If this article helps you push your Nether adventures one step further, that’d make me really glad. Thanks so much for reading all the way to the end!
