I think the whole concept of castle being a building is a little flawed. In Civ III forts were looking like castles at some point and that made sense. After all how is a single castle going to protect the whole city? It's the job of city walls. Castles were designed to protect strategically important spots, not cities. So no for moat as a building, but if castle is going to be one then it could have moat.
