To me though it does look as if they've cheated, you can see in this pic they aren't using real brick work:
I'm fully aware how it is made, and its irrelevent.
What it looks like complete (when the illusion of construction methods and special effect trickery are hidden away) is the only important thing, and it looks like a stone tower. Not a comical interpretation of a stone tower.
They didn't cheat by painting flats, and they used a broad range of colours in painting it to seperate each false stone and give some of them a weathered look. Unlike say, the Pirate splash battle where the "brick" walls have been painted in one flat colour, completely ruining the efforts of the sculpters who bothered to put grooves between each stone...
Disney uses insulation paper to make rockwork on Pirates of the Carribean. Cheap brown paper!
And on Peter Pan's Flight, those clouds you see over the London set are actually sandwich bags suspended on wire!
They could have shipped real boulders cut from a mountain somewhere, they could probably also have found a way to suspend a foggy gas in the air to make tiny clouds too- but they didn't need to, because brown paper and plastic bags were all that were needed to look good
