It’s the last of the Islington phone boxes…for now. I found a few more a year later in November 2017!

I don’t know if there’s a special reason these ones have been painted black, but it looks very striking. It’s also great that they’ve been repurposed for wifi – another good 21st century use for phone boxes.
Somewhere new next week!
Update 5th February 2026: added coordinate link.
