Are you kidding? We spent two nights and I would need months for Istanbul buildings. I spent 4 hours in AyaSophia, until they were closing and wasn't finished. I probably could just stand and sit around the building all day. 1500 years old. Largest church for like 800 years, then a mosque, now a museum. Tons of words and pictures out there, but here is some stuff that struck me.
Well, it is so big it is not easy with a point and click camera to get a picture of the building.
voussoirs (the individual arches) run parallel to the walls and not perpendicular as is most often the case. This is the way I also build vaults, and people point that out implying I am doing it wrong.
Someone checking how it was made? or how it is faring?
Detail of above.
