The thing that looks like a bridge is just the reflection of the railings round the window! I took this from above through a window. Didn't know that this was going to happen!
@pyrrhula that bridge isn't there! I took the photo through a high window of the garden to the side and below. The bridge effect is just the ledge in front of the window with a small metal railing on the window ledge. I don't understand how the reflection came out as it did!
