Question: An 1890s era home (OK, mansion) in my town has a unique window cut into the roof. It’s slender all of 8 inches wide and 30 inches tall it looks like. It’s too small to see much out of, never mind let much light in, and it’s questionable if it has a purpose other than architectural detail.
Answer: I’m always careful of seemingly meaningless details in a home from this age. There always seemed to be purpose underlying the grandeur in what appears to be a Gilded Age home where ornamental detail was paramount.
