We've already learned about parts of the tops of castles, like the Wall Walk where people can walk along the edge of the castle behind a wall, the Parapet which is a short wall and the Crenel which is a small gap in the wall.
Another part of a wall walk on the castle is the Merlon.
This is the opposite of the crenel, and is a higher part of the wall where people can hide behind.
So usually castles would have merlons and crenels right next to each other, so they could hide behind the merlon and attack people from the crenels.
Having a bunch of crenels and merlons right after each other is called crenellation.
