Germans only!

Today was the first of my walks booked on the Autumn Walking Festival.
It was fairly interesting but despite being around town didn’t give me any ideas for my Urban Photography routes. But it’s always good to walk in company.
One of our last stops was at the German Naval Signals HQ which I haven’t visited since the early 60s. Then it was just a bunker used as scout headquarters and I went along for some exercise the purpose of which (as far as I was concerned anyway) was to meet the College boys.
It is now very well presented and interesting to see. These are the urinals...
