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.

Ruined Portal (X -416, Z 224): 172 blocks west of spawn. Check the chest, then complete the obsidian frame to reach the Nether early.
Ocean Ruins (X -272, Z 96): 193 blocks north of spawn. Underwater ruins: drowned can spawn around them.
Trial Chambers (X -480, Z 256): 226 blocks west of spawn. The chambers lie underground: dig down from the surface, bring torches and food, and keep your trial keys for the vaults.
Shipwreck (X -144, Z 592): 324 blocks south of spawn. Search the wreck for its chests and maps.
Village (X -400, Z 704): 440 blocks south of spawn. Beds, food and villagers to trade with: the easiest first base.

Stronghold

The nearest stronghold of the first ring is roughly 1,582 blocks north-west (around X -1452, Z -748). This position is approximate: throw Eyes of Ender to find the exact spot.

FAQ

Where is the nearest Ruined Portal in seed 778913398687907701?

Around X -416, Z 224: 172 blocks west of spawn.

Does seed 778913398687907701 work in 1.21 and 1.20?

Yes. Our tool gives the same spawn and structures in 1.21.1, 1.21.4 and 26.x. In 1.20 the world is the same, but Trial Chambers did not exist yet.

How do I use the seed 778913398687907701?

In Java Edition, click “Create New World”, open the “World” tab and paste 778913398687907701 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.
