Route from spawn

North is negative Z, east is positive X. Press F3 in game to see your coordinates. The coordinates below are those of each structure’s starting chunk, so look around within about 16 blocks.

Trial Chambers (X 656, Z 128): 80 blocks south-west of spawn. The chambers lie underground: dig down from the surface, bring torches and food, and keep your trial keys for the vaults.
Ruined Portal (X 768, Z 240): 187 blocks south of spawn. Check the chest, then complete the obsidian frame to reach the Nether early.
Ocean Ruins (X 800, Z -176): 258 blocks north of spawn. Underwater ruins: drowned can spawn around them.
Shipwreck (X 416, Z 112): 292 blocks west of spawn. Search the wreck for its chests and maps.
Ocean Monument (X 288, Z 144): 424 blocks west of spawn. Guardians attack on sight: bring potions of Water Breathing.

Stronghold

The nearest stronghold of the first ring is roughly 1,556 blocks south (around X 1284, Z 1508). This position is approximate: throw Eyes of Ender to find the exact spot.

FAQ

Where is the nearest Trial Chambers in seed 3404544535694295634?

Around X 656, Z 128: 80 blocks south-west of spawn.

Does seed 3404544535694295634 work in 1.21 and 1.20?

From 1.21.4 on, yes. In 1.21.1 and 1.20 the game picks the spawn point differently, so you start somewhere else in the same world.

How do I use the seed 3404544535694295634?

In Java Edition, click “Create New World”, open the “World” tab and paste 3404544535694295634 in the “Seed for the world generator” field. The coordinates on this page are only valid in Java Edition.

Does this seed work in Bedrock Edition?

No. Bedrock Edition places structures differently, so the same number gives another world. All seeds on Blockaria are Java seeds.

Why are the heights shown as “~”?

Our tool computes X and Z exactly but not the height of each structure. Use the copyable command: it puts you on the surface above the structure.
