This wall is in the alley between a couple commercial buildings right near the center of town. I'm quite sure these are cable TV, er, cables. Which makes me think that there must be a bunch of residential apartments in the upper floors of the building. There's a yoga studio on the third floor, and maybe other businesses I don't know about, but this is quite a lot of cable TV/internet accounts. There are only four or five businesses obviously operating in the building.
