We just learned about Castles and Palaces.
Castles have all sorts of different things that they use for defense or attack.
One thing some castles have is called a Motte.
A motte is like a large hill made out of dirt, with the top part being flattened out.
Usually there was also a ditch around the bottom of the motte, and a castle was built on top of the flat hill.
