Yes, you are right and this is a really wonderful shot. The lights make it look wonderful and s hows detail that might not be seen as easily in a day shot.
You will be led to the knowledge of the internal things which are invisible to you, by the external things which you see before you. . . . Even so then, we can represent to ourselves in thought the Author of all that is, by contemplating and admiring the (visible) things which He has made, and ever brings into being.
