I know there aren't much infos about the real building but when I see this and read the word palace.... Well it looks cool but there just two rooms; and you cannot seperate them in more without destroying the cool walls and roofs; so you would need to stay by this two rooms. But when you do so there is no much place for anything except a throne for example or you could convert it into a church - at least anything with high and huge rooms with not to much inside. To make a cut - I cannot imagine how the building could be used in a good way as a real palace
