Generate Minecraft seeds with four ocean monuments clustered close together — perfect for sponge runs, prismarine hauls, and building a mega guardian farm from one base. Only biome-verified monuments (in deep ocean) are counted, so every cluster is real.
✓ Every seed is verified: four ocean monuments generate in deep-ocean biomes within the chosen radius of a common center.

Open MC Seed View →An ocean monument is a huge underwater temple guarded by Elder Guardians. It’s the only source of sponges, plus a rich supply of prismarine, sea lanterns, and eight hidden gold blocks. A quad monument cluster is a seed where four monuments generate close enough together that you can raid or farm all of them from a single base — a massive time-saver for sponge collecting and the foundation of a large guardian farm.
This finder scans the seed space for exactly that: it counts only biome-verified monuments (ones that actually generate, in deep ocean) and returns seeds where four of them sit within your chosen radius of a common center. Everything is computed with the cubiomes library, so the monument positions are exact for Java Edition.
The search runs entirely in your browser using WebAssembly — no seed is ever sent to a server. Monument positions and biome viability are computed with the cubiomes world-generation library, so the four monuments really generate at the listed coordinates on Java Edition 1.21 (placement is stable across recent Java versions). A free, accurate alternative to Chunkbase.
