All these pictures were taken at the Ihasiye Şerafhan Medresesi, dating to 1429 according to my notes. As a matter of fact it's a whole complex of several graves and a central building, which is the medrese or Koran School (now housing offices of some kind).

Some pictures show details of the central building, some were taken at the grave monuments. They are roughly from the same period and carry names like "Three sisters", but no real information was provided, so I leave it at that.
