We just learned about the Battlements on the top of the castle where people defend from attackers.
Another part of a castle's defense is the Machicolation.
This is a place where the top of the wall sticks out a little and there is a hole where people can drop things down on attackers.
It isn't a low spot in the wall like a crenel, the wall is still high there like a merlon, but it sticks out.
In the old days people would use that spot to drop big rocks or pour hot water or oil on people trying to break into the castle.
One famous machicolation we already learned about is at Blarney Castle in Ireland.
The stone on the bottom of the machicolation is called the Blarney Stone, and kissing it is for good luck!
