We just learned about the small back door on a castle called the Sally Port.
Another part of a castle is a Barbican.
This is a small building on the outside part of the castle that was built to help defend the castle.
Sometimes a barbican has a wall that goes from the barbican back to the castle, that defenders can walk on.
These small buildings would usually have some soldiers in them to help be the first line of defense before attackers could get to the main castle, and also help warn the castle that danger was coming.
