Usually, you have to go pretty far out into the ocean to find an ocean monument. In this seed, you can find one in a loch-like area near the land. Then as a bonus, there is a village on land with a blacksmith and some cool extreme hills nearby.

The Ocean Monument
When you spawn, you’ll be in a forest, but if you walk forward you’ll come to the edge of the ocean. You may have to go a little west along the water, but eventually, you should see a structure under the water. That is the ocean monument.
It’s hard to explore ocean monuments thanks to them being underwater and being full of monsters called guardians, but if you can find some way to survive it, they’re cool places to check out.
The entrance is marked by arches with lights. Inside are halls and rooms that are almost like a maze. If you can find it, there is a treasure room somewhere near the center that has a big prismarine and dark prismarine pillar that contains eight blocks of gold inside.
The Extreme Hills
Since the ocean monument is a bit hard to enjoy due to the difficulty of surviving in it, there are other features you can explore on land too. Back near your spawn point, you can find extreme hills topped with snow. These hills have tall peaks and rock structures that defy gravity. They also have great cliffs and caves to explore.
To the west of the extreme hills sits a village at -311 / 73 / 148. This large village has lots of crops, villagers, and buildings, including a blacksmith’s shop. (And apparently, a horse on a roof, if it spawns like mine.)
The chest in the blacksmith’s shop is full of great items like obsidian, iron ingots, an iron helmet, an iron pickaxe, and a gold ingot.
That is just the beginning of this seed. See what else you can find!
