5 best Minecraft Java seeds for castle-building in 2021

It is common knowledge that a castle in Minecraft is supposed to be quite massive. This size requirement means that players must have a flat and open plot of land to build the castle. The best biomes to build a castle on are Plains, Desert, Badlands, or Snowy Tundra.

A player can obviously build a castle in any biome. However, biomes with more clutter and hills will require terraforming, which is extremely time-consuming and boring. The seeds listed below will give players a great starting location for their dream castle.
