My home town is criss-crossed by narrow walking alleyways. Many of them date from medieval times and would once have been busy streets lined with residential dwellings, shops and inns.
Nowadays, too narrow for traffic, these alleys are only used as shortcuts, and their doorways, windows and shop fronts have been replaced by featureless walls.
Featureless? Yes. Until the advertisers, fly posters and graffiti artists get going…

I’m always drawn to graffiti too especially in unexpected places. Great photos.

Yes, I like graffiti, as long as it has some artistic merit and isn’t just deliberate defacement. Also like the look of crumbling old walls, rusting metal, faded signs, etc. 😄
