Since the castles were so big, they had to house a lot of things right? That is partly correct, partly incorrect. The outside of the castle was simple, high walls to keep invaders out, and bridges. A draw-bridge was a bridge that someone had to lower from the inside of the castle for someone on the outside to get in. If the drawbridge wasn’t down, it was very hard to get into the castle. There were also other obstacles on the outside of the castle making it difficult to enter. There was a moat…a hole dug around the entire castle filled with water. The draw-bridge would lower over this making it easier to walk across. There were also high towers for look-outs to see what was going on outside of the castle. A castle could be beautiful or not very attractive depending on how it was built.
