Here’s another fairly rural box that Mum and Dad found in Wales last September.
(Coordinates 51°97’89.0″N, 5°05’73.9″W.)
This box has been repurposed for a defibrillator now (great news!) – you can see it alongside Dad’s photo-taking reflection in the picture! You can also still see the phone box in its previous tired state in the Google Street View image linked above.
