Reports are that the man who had this built, was never really happy with it, or anything else. I suspect he was just not happy with life, and he tried to make himself happy by building castles, and surrounding himself with nice things. But deep down inside, he was troubled. Things and places don't make you happy. Happy comes from inside. I could be happy in this castle, and I am happy in the much smaller castle I live in.
Are you happy today?
