Witch Hut/Woodland Mansion
Minecraft Seed: -454961508
You spawn in a spruce forest, with a ruined Nether Portal nearby. It doesn’t have exceptional loot, but travel a little bit and you’ll find a nearby swamp with a witch hut at its entrance.
Travel in the same direction and you’ll come across a village, which has a woodland mansion right next to it.
This is all less than 500 blocks from spawn.
