Hello @heroldius! Nice to hear that!

Street Art is spread throughout the city and suburbs. I can point you to a few articles, but you'll need to translate them:

- A few spots, with addresses: https://www.timeout.pt/porto/pt/arte/roteiro-da-arte-urbana-no-porto

- A few spots, with not so exact addresses: https://buenosairesstreetart.com/2018/12/03/porto-street-art-and-graffiti-the-best-murals-around-the-city

- A few routes, long walks but easy to follow: https://streetartcei.com/index.php

In this last adress, you'll find the routes in this menu here:

I hope this helps. Sorry but the stuff I found in English was very incomplete.
