Well plumbed window

Took myself off to Leek today. I love it. Did some bits of shopping and then mooched around the college buildings. I find this window fascinating. It is in the Library building. Next time I am there I must investigate inside to find the source of all the drain pipes!
There are lovely wall panels depicting the subjects studied at the ciollege and I have only just realised that it is only women depicted for each if the different subjects - see extras (more investigation needed).
