A solid part of a wall that is between two openings, often found in castles or fortifications.

Merlon originates from the Old French word *merlon*, meaning a part of a battlement or parapet. It refers specifically to the solid part of a fortification that alternates with the openings (embrasures) for archers or cannons.
Think of the Old French word for a part of a battlement — a merlon is the solid section that protects while allowing defense.
