Ocean monuments are some of the most rewarding structures in Minecraft — massive prismarine fortresses hiding treasure, rare sponge rooms, and blocks of gold. But finding one can take a long time if you're just wandering the seas. These seeds put ocean monuments close to your spawn, so you can get right into the action. Whether you're playing Java Edition or Bedrock, there's something here for you.

Why Farm Ocean Monuments?

Before diving into the seeds, let's talk about why ocean monuments are worth your time:

  • 8 Gold Blocks: Hidden in the core of every monument — worth 72 gold ingots total.
  • Sponge: Found in sponge rooms, sponge is only obtainable here (besides creative mode). Essential for draining water areas.
  • Prismarine & Sea Lanterns: Beautiful building materials with a unique aquatic aesthetic.
  • Guardians: Killing them drops prismarine shards and crystals, plus a decent amount of XP.
  • Elder Guardians: Three per monument — defeating them gives you Mining Fatigue resistance… wait, they give you fatigue. Bring milk!

Ready to get wet? Here are the best seeds.

Seed #1 — Monument at Spawn Island

Seed: 4837753214623827487
Edition: Java 1.21
Coordinates: X: 150, Z: -200

This seed spawns you on a small survival island with a warm ocean surrounding it. Head northwest from spawn and you'll spot an ocean monument in shallow water — visible from the surface on a clear day. The shallow depth makes draining the monument far more practical than usual.

Bonus: There's a shipwreck nearby with a buried treasure map inside.

Seed #2 — Triple Monument Cluster

Seed: 2065486297
Edition: Java & Bedrock 1.21
Coordinates: X: 400, Z: 100 (nearest)

This incredible seed features three ocean monuments within 600 blocks of spawn. The biome surrounding them is a deep ocean with warm patches, giving you a rich environment for underwater exploration. Perfect for players looking to build a full guardian farm.

Bonus: A coral reef sits between two of the monuments, creating a beautiful underwater landscape.

Seed #3 — Village Overlooking a Monument

Seed: -1813740965
Edition: Bedrock 1.21
Coordinates: X: -300, Z: 50 (village), X: -450, Z: -100 (monument)

This Bedrock seed starts you near a plains village right on the coast. A short swim or boat ride north takes you directly to an ocean monument in relatively shallow water. The village gives you a strong early-game base, and the monument is your mid-game objective.

Bonus: The village has a blacksmith chest with iron gear — great for your first monument run.

Seed #4 — Desert Temple + Monument Combo

Seed: 1785852800490497179
Edition: Java 1.21
Coordinates: X: 200, Z: -50 (desert temple), X: 400, Z: -250 (monument)

If you want resources from multiple structure types in one go, this seed delivers. Spawn near a desert, grab the temple loot (watch for the TNT trap!), then sail north to the ocean monument. The contrast between desert and deep ocean makes this seed feel like a full adventure in a small area.

Bonus: Diamonds have been reported in the desert temple chest in this seed.

Seed #5 — Underwater Ruins + Monument

Seed: 3427891234
Edition: Java & Bedrock 1.20+
Coordinates: X: 100, Z: -350

This seed places you near a massive ocean biome dotted with underwater ruins leading toward a monument. The ruins have chests with useful loot — enchanted fishing rods, emeralds, and gold nuggets — making the swim to the monument feel like a proper dungeon crawl.

Bonus: An ocean ruins village (large structure) sits between you and the monument.

Tips for Conquering Ocean Monuments

Gear Up Before You Go

  • Respiration III helmet — Massively extends breath underwater
  • Aqua Affinity — Lets you mine at full speed while submerged
  • Depth Strider III — Move fast underwater like you're on land
  • Turtle Shell helmet — Grants Water Breathing for 10 seconds when at low breath

Bring the Right Potions

  • Water Breathing (8 min) — Mandatory for deep dives
  • Night Vision — Monuments are dark and poorly lit
  • Strength II — Elder Guardians have a lot of health

Deal with Mining Fatigue

Elder Guardians inflict Mining Fatigue III the moment you get near the monument — this makes breaking blocks nearly impossible. Counter it by:

  • Drinking Milk to instantly clear the effect
  • Using TNT for explosive block removal (careful with water physics)
  • Pre-placing TNT-filled holes before engaging Elder Guardians

Drain the Monument

For the easiest possible looting experience, consider draining the water from the monument entirely. Use sponges (from inside the monument itself) or sand walls to enclose sections. It's a big project, but it turns the monument into a regular dungeon.

What to Do After the Monument

Once you've cleared all three Elder Guardians and grabbed the gold blocks, the monument itself becomes a great base. Here's what players often turn them into:

  • Guardian farms — Spawners produce guardians endlessly. Build a farm for prismarine, XP, and fish.
  • Underwater base — The prismarine structure is already impressive. Add glass domes, interior lighting, and rooms.
  • Aquarium build — Fill surrounding areas with fish, coral, and sea life for a stunning ocean exhibit.

Ocean monuments are one of Minecraft's most unique challenges — and these seeds make them easier than ever to find. Suit up, brew some potions, and dive in!
