This is a hallway in Sterling Memorial Library called "Cloisters." The entire library was modeled to look like a cathedral right down to the circulation desk at the "altar."
I will try to get some more of Sterling from the inside but the light is very low and I failed pretty miserably today. I did come away with this photo, which itself is difficult in the best of conditions. Every lens I have ever had showed the bloom in the near-side window. Today was overcast and rainy, so if this is still showing bloom this is as good as I will ever do.
If you look at my shot from Day 7, that hallway is behind me and through a doorway, and you can see in that photo the start of Cloisters.
I love this place. Much better than a photo will ever do it justice.
