We just learned about the Meurtrière.
Another type of castle fortification is the Fujian Tulou.
This is a circle shaped building that is made out of dirt that is packed in tight, and mixed in with stone, bamboo and wood.
On the inside of the building are rooms for people to live in.
The top part of the buildings has gun holes to help fight against people that are attacking.
