Minecraft wiki entry for Hiding_chests, associated text: Some people, however, might know about the above door hideout trick and close the door. BOOM, Loot! Just to make sure they don't find it that way, you can try the above Chest-under-Chest trick or place your chest in the ground and put a wall for the door to block. Now, when they shut the door, they see a plain wall. If you still aren't feeling safe, place it a block under with dirt on top.
