Not-Quite
- Mt. Olympus, home of the Greek Gods. It is a palace that is high above the clouds, so it is sort of a floating castle, but reference is made to "the topmost peak of many-ridged Olympus", so it's not exactly a floating castle. Also, Zeus claims that he hand the earth and sea from a pinnacle of Olympus, so it's not exactly clear what it is.
