It is a traffic light in a broken pole, to a degree it seems lying on the garden. I found interesting how a traffic light could work in such conditions and look as if nothing.
Ths slanted buildings are a bit unsettling. And I would expect the semaphore pole to be parallel to them; after all, up is up! It probably makes sense to you as the photographer, but is difficult for me as a viewer to understand. On a more positive note, I think the exposure is great and the depth of field is perfect.
Great night! Fascinating angle; really caught my attention! Like how the stoplight pole divides the photo. Wish you went for a larger size, would have been great to see the details. Might be a bit of a strech on the garden theme, but what the heck. =-)
