Well, what this is, must be obvious. I can well stand the sight of blood, because it is hard to travel in Turkey without running into a type of display that is a bit more in the open than in Europe, where things are much more sterile. The repetition of stomachs, heads, lungs and all that can be pleasing to the eye, and makes for good pictures, again, if you can stand the sight.
The pictures were taken before the building was restored and put to new use, in 2010 I found it clean and rather empty. In 2014 it housed sellers of all sort of stuff, but no meat was in sight.
