An embrasure is a type of opening or nook that is usually found in a wall, usually in a fortified structure, such as a castle or fortress. It's often designed to allow a person to shoot arrows, guns or cannons through from a safe place, in order to defend the building. In simpler terms, it's a small opening or window-like structure that offers a strategic advantage in a battle or defense situation.
