Mossy Stone Brick Wall is a decorative stone-brick barricade added to Minecraft in Java Edition 1.14 and Bedrock Edition 1.9.0. The block generates naturally inside ruined portals scattered across the Overworld, where the moss-veined texture blends with the weathered stone blocks and crying obsidian of those ruined frames. Hardness sits at 1.5 and blast resistance at 6, so Mossy Stone Brick Wall survives creeper blasts but yields quickly to any pickaxe. Mining without a pickaxe drops nothing, and the wall is non-flammable and non-renewable in the strict sense, although moss can spread onto plain Stone Brick Walls over time in player-built ruins.

Mossy Stone Brick Wall is crafted by placing six Mossy Stone Bricks in the bottom two rows of a crafting table, yielding six walls per recipe, or by feeding one Mossy Stone Brick through a stonecutter for a 1-to-1 cut. Builders reach for Mossy Stone Brick Wall whenever a structure needs an aged, weathered look: castle courtyards, overrun dungeons, jungle temples returning to nature, and decorative garden borders that pair cleanly with Mossy Stone Bricks, Mossy Cobblestone, and stone buttons. The 1-block-tall connectors snap Mossy Stone Brick Wall into corners and gateways just like every other wall family in Minecraft, so the block slots into medieval and ruin builds without learning a new placement rule.
