I remember back when I was young that I saw an episode of Smurfs featuring a castle that disappears and reappears each few centuries and when, more recently, I thought about the whole concept of something disappearing and reappearing like this I became somewhat interested in stories with it. So are there any such stories and where can I find them?
EDIT (In order to clarify some things): First, I edited the title some time ago to say what kind of stories I'd like answerers to talk about after a commenter asked what kind of stories I want (I limited the category of stories since it's big). Also, by disappearance I mean vanishing into thin air in such a way that something no longer is anywhere in this world (not even behind fog/mist, under water or hidden in general). It's seemingly non-existent or in some kind of "Nothingness" area.
