I saw a similar idea somewhere, but what caught my eye was the structure itself. It was Alice in wonderland when she meets the worm smoking a water pipe: there is a path to follow with a castle at one end.
The path is in fact a rampart turned on its side, Oxford and Cambridge in one image below and a palace taken on a visit to Venice. I bought the image of a waterfall from Dreamstime (www.dreamstime.com).
It is an unfinished idea because what is needed is the picture of Alice looking at the waterfall.
