This is the castle that William the Conqueror built before he left to conquer England, to defend his own territory in Normandy, in France. William built this castle around 1050 AD. That’s about the same time as he built the Abbaye aux Hommes and the Abbaye aux Dames.
Like other medieval castles, the Caen castle had a moat around it. The moat was very deep so that enemies could not batter down the walls on the other side. If they climbed down into the moat, it would be easy to shoot them with arrows or drop rocks on them to kill them.
The only way you could get into the castle was by crossing the moat on a wooden drawbridge. Here is a picture of one of the drawbridges (this was such a big castle that there were a lot of drawbridges).
When enemies came, the people in the castle pulled up the drawbridge so nobody could get in. When you went over the drawbridge, you also went through a big strong wooden door, with an iron gate called a portcullis in front of it. The portcullis is gone now, but you can still see the slots carved in the stone wall for the portcullis to slide up and down.
If enemies did get through the portcullis, they would still be in the little hallway you can see in the back, trying to break down the wooden door on the other side. People inside the castle could drop rocks and pour boiling water on them through holes in the ceiling.
Once you were inside the walls, you would see a lot of buildings that were used for different things: barns, toolsheds, chicken coops, houses for people to live in, meeting halls and courthouses, big halls for people to eat in, and many workshops for carpenters, weavers, and so on. This building is a meeting hall that was mainly used for people to come pay their taxes or to discuss money questions with William’s treasurer.

This castle, and other ones that people built in Europe about this time, look a lot like the castles and city walls people were building in the Islamic Empire. Compare William’s castle to the walls of Cairo, in Egypt, built about the same time.
