Bombs away

This old bunker, a left over from the war, is being ‚renovated‘ and will eventually be a number of apartments, great location but I‘m thinking the daylight (or lack of) might be an issue.
I got shouted at taking this picture, I’m guessing the builder on the ground level way beneath me was worried that I‘d got him in shot (and this is why I’m reluctant to do much street photography here...)
