Shout out to Aberdeen, Scotland, it has some amazing Street Art these days, so worth a look. We've a great local scene and have also had a few years of Nuart festival, which has created some real stunners.

There is a massive gallery at https://streetartaberdeen.org/gallery

And a map view at https://streetartaberdeen.org/

The streetartaberdeen.org is a platform I created to document and locate street art, if anyone is interested it is all OpenSource and could be replicated for other cities.
