There was - in the upstairs part of the museum where they still have some space to spare - an exhibition of works of pupils from the Özel Yüzyıl Ilköğretim Okulu (a school for primary education). Works were obviously inspired by the objects in the museum, and overall they were fun to see.
Through the window you see the Çinili Köşk, where for the same ticket you will see great Iznik (and other) tiles and such.
