Fountains Abbey, on a very foggy night. Quite a magical experience when lit up. Check the website for when they do it: wander the ruins at night with Gregorian chanting in the background..
A note on the white balance here: the orange glow comes from the big sodium lamps, accentuated by the light reflecting back from the thick fog. This is, more or less, how the human eye saw the scene. I did do an edit of these where the white balance was set to make the scenes look more blue and "natural", but the fact is, that's not what it looked like in person, hence why I have decided to go with the "orange" look.
