Thanks, lifeasdaddy - you found the same place to take the photo!
The original photograph had sat in my favourites file for a long time. Firstly because of the beautiful symmetry, and secondly so I could one day take a comparison shot.

Then one time I was passing behind the place from where my photograph was taken and discovered there is a locked door to the balcony I wanted to access, but that the door has paynes of glass. I took this pic through the glass, no special access required.
And here is an even earlier reading room:
