Happy New Year!
This is an in-progress rendering of what I envision the iconic central castle for this park looking like.
The castle here (Princess Anna) is heavily-inspired by the one in 'Frozen', although it is not meant to be a re-creation. In many cases, I think it is more effective for park architecture to be its own thing, versus directly re-creating a film world.
The view you are seeing is from the Fountain Show viewing area, so it is technically the left-side of the castle: the front view would be facing the causeway and main courtyard gate.
The focus of this illustration is on the architecture (leaving the equally-important rockwork mountain and landscaping for later). The field of view is within the 'Outer Sea Wall' (see red line). I will probably continue this drawing to show a wider view with Sea Wall & towers. You will note the flagship flume attraction 'Once Upon a Time' passes around and beneath the castle.
I imagine this castle could serve numerous functions:
-Premium, table service dining on the upper floors, with views over the park (note the big triangular, glass window).
-Walkthrough attraction, exploring various chambers.
-Meet & Greet
-A dungeon housing an Ice Dragon (or some sort of winter creature), inspired by the Paris walkthrough.
