This is the Arasa Mosque. I took a picture of the placard over the main entrance which gives some details, but translating will take a while. And I will never understand how Turkish "keepers" of monuments dare put ugly plastic notices on spots where they utterly ruin the architects design for an ornate entrance. They seem to have a blind spot for such destruction, which is what it amounts to. Here you can see for yourself. But note: this is just one example of many, all over the country.
