Watercolor Roof
Still on the topic of unique architecture, this roof is definitely one-of-a-kind, as it has the appearance of a set of watercolor paints. Looking at the picture, one can see different colors including green, black, white, a shade of brown, and something that looks like burgundy. Another look at the picture will help you spot what resembles thread-like structures.
Quick research, however, shows that this is not the photo of a roof, but a satellite photo was taken from above. This clarifies the actual state of the watercolor roof as massive pools of some sort. The thread-like structures beside the pools can also be discovered to be roads on further inspection.
