Castle Shift

🏰 Castle Shift - Castles in Your World

Discover stone brick castles naturally generated across the landscape!

Castle Shift is a structure mod that adds multi-story castles to Minecraft's world generation. Each castle features randomized structural variations, so no two castles are exactly alike.

✨ Features

🏗️ Multi-Story Castles

• 4-Floor Structures: Grand castles with walls, towers, and corridors
• Natural Placement: Castles generate organically in a wide variety of biomes

🎨 Randomized Materials

Each castle's roofs, walls, and stairs are built from materials randomly selected per castle, so no two castles look the same!

• Roofs: Spruce, Dark Oak, Deepslate Bricks, Dark Prismarine, Red Nether Bricks, Crimson
• Walls: Stone Bricks, Deepslate Bricks, Polished Blackstone Bricks, Sandstone, End Stone Bricks
• Stairs: Bricks, Stone Bricks, Polished Granite, Deepslate Bricks, Polished Blackstone, Polished Blackstone Bricks, Red Nether Bricks

🧱 Structural Variations & Weathering

• Multiple Templates: Each floor section (walls, corners, centers, towers) has multiple structure templates chosen at random
• Wall Weathering: Stone brick and polished blackstone brick walls may randomly degrade into cobblestone, andesite, or cracked variants for a lived-in look

📦 Datapack-Friendly

• Structure placement can be customized via datapacks
• Adjust spacing, separation, and biome filters to your liking
