Walls are tiles that create backgrounds on top of biome backgrounds. Walls are hiding behind everything else, such as blocks. Some types of walls are naturally generated at world creation, being abundant in certain biomes. They are one of the main components a Terraria world consists of alongside blocks and liquids. The player can also place walls manually on any tile which does not already contain a wall, given that it is adjacent to another wall or block. Walls can be removed with a hammer or explosives.
