Certain blocks in Terraria only appear in the Background, such as walls, Crystal Hearts, and Shadow Orbs. Background blocks can be destroyed and collected with hammers. In addition to blocks, furniture is also placed in the background. The only background block(s) which can't be destroyed with a hammer are Trees. Trees can be chopped down with an axe.

Walls Edit

Walls are tiles placed in the Background. All walls except for dirt walls and dungeon walls prevent Monsters from spawning in the area in front of the wall, and are therefore useful for preventing monsters from spawning inside player-made buildings. Walls do not prevent players or monsters from passing through (but blocks do).

There are several different types of walls. With the exception of dirt walls (described above), there is no difference between them other than their appearance. Walls can be placed in the Underground layers once stones start to appear in the background. (This area is particularly easy to notice if you have Parallaxing on.)

One brick will craft 4 wall blocks of that type. Placed wall blocks can only be broken with a Hammer. Naturally occurring dirt walls generally need to be destroyed from the outside in (i.e., you cannot knock a hole in the naturally occurring dirt wall deep underground). The best way to calculate how many walls you require for a room or house is to find the dimensions of that house/room. Then to obtain the area using the dimensions. Area/4 = about the amount of walls you need. To break down these walls, a player must start from an opening, not from any place.

Special Walls Edit

These walls can only be obtained though the destruction of the dungeon background with a hammer, hamaxe, or explosives. Explosives will only destroy the walls that aren't blocked by the actual bricks, because dungeon bricks cannot be destroyed with Bombs or Dynamite.

Furniture Edit

Blocks and furniture in the background do not affect the player's ability to move, except most allow you to stand on them, like the Wood Platform.

Back Drop Edit

A back drop is a lot different than the actual Background itself. The background lets you place a lot more in it than the back drop. For instance the wooden platform can be placed within a background, not a back drop. If you however try to place a wooden platform in the back drop nothing will happen, because the back drop is the outside world and it would not give a good sense of realism if there was a wooden platform floating in the sky.

TriviaEdit

Ebonstone and Hellstone walls exist ingame, but only in naturally generated Corruption chasms and Hell Shrines, respectively. The item, however, does not drop, making them unobtainable. Another type of unobtainable Mud Background Walls were added in the 1.0.6 patch, and are generated within a 1.0.6 and above world in the Jungle, you however can not craft them, even though the change log says you are in fact, able to. They cannot be obtained as of the current update.

Breaking mud background walls with a Hammer/Hamaxe will turn them into "dust" much like Dirt walls, Hellstone walls, etc.
