A Cobblestone Wall is a decorative and functional block made from Cobblestone, offering a sturdy alternative to fences for enclosing areas. It connects seamlessly with other walls, fences, and solid blocks, making it useful for creating barriers and detailing structures. Cobblestone Walls can be mined with any pickaxe; otherwise, they drop nothing.

They naturally generate in woodland mansions, pillager outpost towers, and various village structures in plains, taiga, and snowy tundra biomes. Players can craft them using Cobblestone or obtain them through stonecutting. When placed under a note block, Cobblestone Walls produce a bass drum sound.
