Having recently come across the photography of Michael Wolf (http://photomichaelwolf.com), I was inspired to search for my own taxonomies in the Catalonian city of Barcelona. As humans, we are fascinated with grouping, structure and categorisation; as my worn sandals hit the pavements of the Spanish city, I found that the symmetry offered in a tower block of flats appealed to something primitive in me. Ironically, the artificial functionality of man-made structures seemed to feed my natural love for order, a numerical side of what makes us human.
Please note I am an amateur photographer and took these images on my Google Pixel. I would love any feedback or tips off fellow photographers!
