Banners (decorative)

Banners are decorative furniture items that can be placed on the underside of blocks. There are four crafted Banners (red, green, blue, and yellow). There are also several that are found naturally placed in various biomes, or are dropped from enemies. All Banners are purely decorative, and have no function.

Banners that drop from enemies are known as Monster Banners. Nearly every enemy in the game has a corresponding Monster Banner, which it has a 0.5% chance to drop upon defeat.

Faction Flags are Banners found in Dungeons. In post-Plantera worlds, the Faction Flags found hanging in a particular Dungeon area correspond to the background wall type (brick, slab, or tile), both of which signify the types of enemies that will spawn there. See Dungeon for more info.

Placed
These Banners are found naturally placed in certain biomes.

Orientation
Each banner may be placed in a right-facing orientation or a left-facing orientation, but this is not decided by the player. A banner placed in a specific "column" in the world will always face one specific direction, no matter the height. Placing it one block to the left or right will flip the orientation, resulting in alternating left and right facing "columns" which decide the banners' placement. Two identical banners with an even number of blocks in between each other(including zero blocks) will always face different directions, while banners with an odd number of blocks in between each other will always face the same direction.

Trivia

 * The four craftable banners correspond to the team colors in multiplayer.
 * There are 6 Dungeon Banners, 3 Floating Island Banners, 6 Underworld Banners, 3 Pyramid Banners, 46 Normal Monster Banners and 41 Hardmode Monster Banners. Totalling 105 Non-Craftable Banners as of v1.2.4
 * The Lihzahrd Temple related enemy banners can be obtained before hardmode as long as you have already obtained a Picksaw from Golem, otherwise, Plantera must be defeated and have a temple key as one of its drops, most restricted areas with highly unminable blocks also follow this principle.
 * The left half of the Nymph Banner is of the Lost Girl NPC, while the right half is the Nymph monster.
 * Bosses don't have banners- instead they have trophies.
 * The Nymph Banner is a rare drop from the Nymph, the rarest enemy in the game, making it the rarest item in the game.
 * If you manage to defeat Skeletron and you need coins, take of all the banners you find in the dungeon. Each banner sells for 20 silver, and five banners will make one gold coin.
