Minecraft Mushroom Island Ocean Monument Seeds
By the ChunkScan Team · Updated August 2026
Mushroom islands sit in the open ocean, and ocean monuments are built in deep ocean, so the two can end up close together. These seeds give you a safe island to live on and a monument to raid or farm. Every seed below was scanned and has a mushroom island and an ocean monument near spawn. Of the Java 26.3 seeds we scanned, 9,948 have the biome within 512 blocks of spawn and the structure within 1,000 blocks; for half of them the structure is 524 blocks away or closer. Versions with at least 12 such seeds in our scan: 1.18, 1.19, 1.20, 1.21, 26.2 and 26.3.

A safe island next to a guardian farm
Ocean monuments give prismarine, sea lanterns, wet sponges and eight gold blocks hidden in the core. Elder guardians drop wet sponges and prismarine, and a drained monument makes a strong guardian farm. The mushroom island nearby has no hostile mob spawns, so it is a safe place to sleep and store loot between dives.
Can an ocean monument spawn next to a mushroom island?
Yes, if there is deep ocean nearby. Monuments only generate in deep ocean, never on the island itself. On these seeds the monument is within 1,000 blocks of spawn, so check the seed map for the exact spot.
What do I need to raid an ocean monument?
Bring water breathing potions or a turtle helmet, and milk to clear mining fatigue from the elder guardians. Doors and boats give air pockets. Respiration and depth strider make it much easier.
