We're still at Richmond Palace. I hope you enjoyed discovering the comment about the 16th C flushing toilets in the wiki notes.
I chose this rather harsh looking treatment for the B&W photo because I wanted to enhance the texture of the ancient brickwork - which is also why I took the photo. You can clearly see remnants of the very old structure (filled in arches). I guess that what we are seeing here are windows put in during a late 17th or early 18th C development. I also notice that a car roof has sneaked in.......arrrrgghh!!! The grey overcast weather (cloudy but surprisingly warm) was ideal for B&W photography.
