Wall

A wall is a decorative block. Like fences, they can be used to block off areas, as players and most mobs are unable to get over them.

Natural generation
Cobblestone walls generate in woodland mansions. They also generate in pillager outpost towers, and in some houses in plains, taiga, and snowy tundra villages. Snowy taiga villages also generate with cobblestone walls.

Mossy cobblestone walls usually generate in pillager outposts, occasionally taking the place of cobblestone walls.

Diorite walls may generate in snowy tundra villages.

Sandstone and granite walls may generate in desert villages.

From block loot
Walls can be mined using any pickaxe. If mined without a pickaxe, they drop nothing.

Info
Walls are one and a half blocks tall for player/mob collision, and one block tall for all other purposes, similar to fences. This prevents players and mobs from jumping over them, while using only one actual block space. A wall occupies the center space of blocks. A wall block automatically connects to any adjacent solid block, and its top rises slightly to support any block immediately above.

Because the hitbox of a wall block is smaller than a single block, it allows a mob in the block to breathe even when submerged (if it is not waterlogged.)

Walls are more efficient at fencing off mobs than a two-block high wall of cobblestone, costing half as many blocks, and being more space-efficient as well. However, a skeleton might shoot over the wall, a creeper could explode if a player is standing near the wall and a spider could still climb over the wall.

Unlike fences, if two walls are placed one block apart diagonally, the player cannot walk between them.

Breaking
Walls can be mined using any pickaxe. If mined without a pickaxe, they drop nothing.

It is not known if other walls have different mining times.

Block data
In Bedrock Edition, cobblestone wall uses the following data values:

Trivia

 * When a fence gate is placed next to a wall, it stoops down slightly to match the height of the cobblestone wall.
 * A stack of cobblestone made into cobblestone walls (which use only 60 of the 64 cobblestones) makes exactly enough walls to fence off one chunk. However, using a stonecutter can make 64 cobblestone walls without any cobblestone left, rather than 60.
