Well, maybe you were taught that, but I find it hard to believe that everyone in America is taught something so fundamentally wrong. First, while a king may live in a castle, there is no requirement that a castle has anything to do with a king. A castle is a heavily fortified structure that almost always has thick, strong walls. It may be essentially one building, in that everything is internally connected, or not, with many buildings inside the walls. There may be a town or city outside the walls, or not. That town or city may, or may not, have a city wall, but that is not part of the castle.
A good example is York, which had both city walls (most of which are still there) and a castle (most of which is gone): https://en.wikipedia.org/wiki/York_Cast ... iorama.JPG
. The furthest structure, with it's own moat, is the keep, which is the final fortified retreat if the rest of the castle is overrun. An oddity of York castle is that the keep is actually outside the main castle walls, which is not usually the case.
