Ocean Seeds
Ocean Monument Seeds Close to Spawn
An ocean monument is one of the few structures that rewards a full raid: eight sponge blocks, a gold block behind the Elder Guardians, and a safe base once the mining fatigue casters are cleared. The catch is that monuments generate in deep ocean, which is rarely where you spawn. These seeds put a monument within a few hundred blocks of your start, so you can gear up on land and swim out early instead of sailing for thousands of blocks first. Every coordinate below comes from an actual world-generation scan, not a guess, and each seed pairs the monument with the shipwrecks, ocean ruins, and buried treasure that make an ocean start worth committing to.

What makes a monument worth the swim
Ocean monuments spawn only in deep ocean biomes and are guarded by three Elder Guardians that inflict Mining Fatigue III, which cripples block-breaking until you kill them. The payoff is real: eight sponge blocks in the sponge room for instant water removal, a single gold block sealed behind each Elder Guardian, and prismarine plus prismarine crystals for building and lanterns. Regular Guardians drop prismarine shards and the occasional fish. Because the whole structure sits underwater, the practical requirement isn't distance alone, it's whether you can reach land nearby to build up potions of Night Vision and Water Breathing before you go.
Why proximity to spawn matters
A monument 3,000 blocks out means a boat trip, a night on the water, and no easy resupply. A monument a few hundred blocks out lets you use your spawn area as a staging base: mine for the pickaxe and armor, brew potions, drop a bed, then swim out and back in a single session. Every monument in this list is close enough that the surrounding land structures, villages for beds and food, ruined portals for a Nether shortcut to blaze rods, stay in range too. That turns a monument raid from an expedition into an afternoon goal.
How ChunkScan verifies each monument
These aren't community submissions. ChunkScan runs the same world-generation algorithm Minecraft uses, then records the exact block coordinates of every structure it finds. When a seed reports a monument at (-256, 16), that position was computed from the seed's structure placement, not observed by a player who might misremember. Distances shown are straight-line from world spawn. Out of more than 1.7 million seeds scanned, only 20 match this topic's filters, and of the ten shown here just three contain an actual ocean monument. The rest are strong ocean starts built around ruins, shipwrecks, and treasure, which is worth knowing before you pick one for the monument specifically.
Seed -9223069229256200242: the closest monument
This is the standout for a fast raid. You spawn on a beach, which means water is already at your feet, and the monument sits at (-256, 16), just 182 blocks away. A ruined portal at (-480, 96) is the nearest structure at 86 blocks, giving you a quick Nether route for potion ingredients, and buried treasure waits at (-327, 249). A village at (-528, 288) and trial chambers at (-384, 320) round out the area. Grab the treasure map heart of the sea path if you want a conduit, then use the village as your potion-brewing base before the swim.
Seed -9223103620573813429: monument plus a full structure cluster
Spawning in forest, this seed clusters everything east of spawn. The monument is at (176, 80), 222 blocks out, and it shares that corner with an ocean ruin at (176, 128), a shipwreck at (160, 176), and a ruined portal at (192, 192). Trial chambers sit at (160, 304). Because the shipwreck and ocean ruin are between you and the monument, you can pick up a buried-treasure map and salvage loot on the way out, then keep the wood-rich forest at your back for boats and building materials. It's the most self-contained ocean start in this group.
Seed -9223251885608871266: farther monument, richer early game
The monument here is at (272, 64), 400 blocks from spawn, farther than the other two but still a single swim. What makes this old-growth birch forest seed interesting is what's near spawn instead: trial chambers at (288, -432) only 97 blocks away, a shipwreck at (176, -256), an ocean ruin at (112, -256), and two ruined portals. Clear the trial chambers first for early copper, keys, and potentially a decent enchant, then head south to the monument once you're geared. Treat the monument as the mid-game goal rather than the opening move.
Ocean starts without a monument
Several seeds here match the ocean theme but have no monument in range, so choose them for a different reason. Seed -9222840161220616214 (plains) offers two ocean ruins at (-192, 96) and (-304, -208) plus a shipwreck. Seed -9223209819533552518 (snowy taiga) stacks two ocean ruins and two shipwrecks for salvage-heavy exploration. Seed -9223129902761544182 (savanna) puts trial chambers just 35 blocks from spawn alongside ocean ruins and a shipwreck. These are excellent for buried-treasure hunting and early underwater loot, just don't expect sponge or an Elder Guardian fight nearby.
Practical tips for the raid
Brew Water Breathing and Night Vision before you leave; the monument interior is dark and deep. Bring milk buckets or a way to wait out Mining Fatigue, because you cannot mine prismarine at normal speed until all three Elder Guardians are dead. A sponge and a bucket clear water fast once you're inside. Use the shipwrecks and ocean ruins these seeds place near the monuments to collect buried-treasure maps first, a heart of the sea plus eight nautilus shells builds a conduit, which grants underwater breathing, night vision, and mining speed in one placed block, effectively solving the monument's biggest problems.
