This is a great example where a good tilt shift lens can come in handy. I was able to get the whole fountain form a single spot, just by shifting up and down. I still had to tilt a bit up, but that created only a very minimal distortion.
Btw. I a bit unsure on the brightness of my latest photos. The Surface Pro 4 display is different to my standard one I work on regularly, so it will take a bit getting used to it.
