WW2 Radar Base

I often pass this. I have thought about photographing all the remaining military buildings that remain. I can remember the one on the Arley Straight still working in the early 196o's. I never understood why they were so low.
We had just been to have a look at Christmas trees, I wasn't sure if we were having one this year. Liz says we are! I'm picking it up tomorrow with my trailer.
