Minecraft wiki entry for Shelters, associated text: Just like cave systems and bunkers and Castle tower. Hill forts are forts that can be made by strong or earth-made materials such as dirt or stone. Unlike castle or an outpost tower,hill forts have better defenses and you can create your own cave system for hidden base and hidden storage for your important stuff. You can also create your bunker directly within the fort or near the fort. Hill forts are better for PvP bases and raid farming since you can hide magma blocks under a trapdoor and make a lava flow.
