The backside of the castle certainly bears resemblance to its inspiration, Neuschwanstein Castle. It makes me wonder if the primary reason Walt was okay with the top’s reversal was to give Disneyland’s Castle a better shot at an identity of its own. I’d say it worked, if so.
I do maintain my position that the backside of the castle is severely under-appreciated. In support of my argument, I present you this lovely view.
